Vudoo with CCI SV ??

I will be purchasing a 22LR bolt rifle in the near future, and I am strongly considering the Vudoo. I do not compete, but I have grown to appreciate well-made / accurate rifles.

I currently have a KIDD, which shoots fantastic with CCI SV's, so I have a stockpile of that ammo. I also have a lot of Federal Ultra-Match, which also performs well in the KIDD.

I watched a video on the Vudoo website, which states their rifles will shoot non-match ammo. I have also seen a video on Youtube with a fellow shooting CCI SV's, and the ammo performed very well in his Vudoo.

However, I spoke to a super helpful and very friendly rep at Vudoo today and he advised against shooting CCI SV's in a Vudoo. He indicated that using non-match ammo too often could ultimately damage the bolt. He explained it very well, but I must admit I did not completely understand what exactly could be damaged.

So ... I am wondering if any of you have used CCI SV's in your Vudoos. If so, have you experienced any problems with it.

    My Vudoo will not chamber CCI SV or Eley Ammo. The chamber was cut specifically for SK/Lapua so to get CCI SV to properly feed you are really jamming the bolt and crushing the round to get it fit into the right headspace and all that.

    If you want something well made and to shoot CCI SV, I'd say go get a RimX and choose a barrel with a generic chamber that feeds everything.

    Thanks -- good suggestions.

    Of course, I do not intend to shoot CCI SV exclusively. But I was hoping to have that option, since I have so much to it.

    I realize the Vudoo is built for better ammo, just unaware that it cannot shoot non-match ammo.

    kinda funny, im thinkin about buying a Kidd to shoot the CCISV and Fed Ultra i have stockpiled. I bought a bunch when i was working with a RPR, which was a pointless exercise. anyways my vudoo will chamber eley, and eley match and cx shoot similar, all depends on the specific lot. My Vudoo will chamber CCISV with some force, but i dont shoot SV in it anymore, maybe fine, just feels odd.

    i wish you Kidd guys would post more about your rifles, maybe submit a 6x5.

    Working up to it. 5x5 shot in 10-13 mph wind. This Kidd ULW barrel loves CCI SV.

    Op....CCI sv hits the exact same place Center x does out to 150 at least. Im guessing further as its trajectory is identical. Groups are 30-50% larger than center x. Some tight chambering with about 3-4/10 CCI sv.

    CCI SV is cheap bulk 22lr.
    Cody at CCI has stated it is intended to average 2 inches at 100 yards for a 5 shot group.
    Average. Some worse, some better, but average 2 inches.
    So expect strays and outliers... it's hunting and plinking ammo
    for use when results aren't all that important.

    You can see the random flyers in those groups which is typical of CCI SV. Sure, it's better than the bulk pack stuff from Walmart but it isn't competitive enough to win matches.

    Once in a while I will run Automatch in my Vudoo when shooting 2 MOA steel and it's good enough for that type of fun but I haven't tried it on paper.

    Agree with the random flyers but for a bulk/practice ammo it is excellent.
    Posted it as more of a testament to how well the Kidd ULW barrel shot more than anything.
    YMMV, happy shooting

    I have 2 vudoo’s in 22lr. They will both chamber (without a hard bolt close) cci sv from the lot that I have about 15k of. I have tried other lots and it is hit or miss. If they will chamber without a hard bolt close you are good to go. Accuracy wise, depends on the lot. The lot I have is very acceptable at 50 (moa or slightly better) vs .2’s and .3’s with center x. 25 yards you can tell any difference in the groups. 100 yards the non match Ammo falls off very fast. Fine to plink but won’t maximize the potential of your vudoo.

    If it chambers cci sv isnt going to hurt your rifle. For training on steel I run cheaper ammo too. In my Rim X the lot of cci sv i have shoots better at 200 yards then the lot of center x and the lot of eley Tenex biathlon I have. Its on par with 1 of my lots of SK rifle match and the SK pistol match I have. For prs comps past 100 yards the consistancy of ammo by measuring or velocity spreads doesnt necessarily coincide with accuracy. The cost of ammo doesn't mean anything either in my testing.
    At 50 yards it is different that lot of center x is lights out. Cci is ho hmm.

    OP... This is my plan for my Vudoo. I have plenty of CCI Standards for Plinking backyard shooting to be able to save the nice Match Ammo for matches. The CCI won’t shoot as well as others have said, but knowing that going in you will be ok in using it for practice ammo. I had that discussion with Vudoo when I placed my order. I currently do the same thing in my Bergara. It helps to clean the Bore & Chamber before a match to get the crappy gummy lube from CCI out of the chamber.

    Agree, and I am always pleasantly surprised at how well the cci sv does shoot.

    Thanks for all of the responses.

    Since I would like to have the option of shooting CCI SV --- And since some Vudoos cannot even chamber it --- I think I will consider getting the T1X or the Bergara B14R

    For me, the Tikka would need a stock (KRG Bravo) and bolt handle (Sterk), while the Bergara would need a trigger (Trigger Tech). However, I would still be spending quite a bit less money, and I would be able to shoot all of my ammo.

    The Vudoo will chamber the CCI SV but might not pull a live round out. The bolt will close a little tighter. My Bergara bolt is a little tight on CCI SV. I also had an instance where I couldn't extract a SK Match round and had to send it down range. There is going to be that chance with the precision rimfire chambers of todays rifles either way.

    Interesting, not sure I’ve tried to extract.

    But I would assume the Bergara's chamber is not nearly as tight as the Vudoo's -- Correct?

    Judging by some of the stuff I've seen online since the V-22 repeaters were released, it's pretty obvious that some guys don't think twice about keeping the bolt lugs on their Vudoo bolts lubed, nor do they consider cleaning the action & barrel regularly to be very important. This statement isn't aimed at anyone on this particular thread, just what's obvious in reading hundreds of replies here and on other sites over the past few years. Hard for me to understand how anyone could plunk down the price of a precision custom 22RF rifle and then skimp on taking care of it, but maybe some guys just don't love their rifles like others obviously do. Point is, if you're wanting to shoot cheap ammo through a precision rifle like the V-22, you'd better be prepared to take good care of that rifle. Kinda like someone buying a new Corvette, then skimping by using the cheapest motor oil they can find at Wally World in it...

    All I know is it is a Match chamber and Vudoo will tell you not all live rounds can be extracted from the chamber.

    Cci sv in a 10/22 with a shaw barrel. This is just the first random pix I found.
    The chamber shaw uses works without fail and when properly fouled in from clean will produce average 1 moa no problem.

    That special chamber works with any ammo but doesn't produce super tight groops as with a match setup.

    But 2 moa, not at all.

    At the time of purchase the shaw barrel was 100 dollars .

    Thanks all

    In my case, it seems like it would be best for me to get a T1x or a B14r --- While not at the level of a Vudoo, both the Tikka and Bergara seem like darn nice rifles, and they are probably a better fit for me.

    In addition, I have seen some really good groups/performance with the Tikkas/Bergaras since I started my 22lr bolt rifle journey.

    You won't be disappointed in the Bergara. I sure am not in mine. I just ordered a Vudoo as I want a Vudoo as well. That being said I out shot 2 Vudoo's at this past weekends NRL22 Match. Those same guys will be there on the 21st and we will see again how well I can do. In match conditions the shooter causes his misses. I had a BAD Match for January.

    Did you leave your Bergara in the factory stock?

    I have not handled the Bergara stock, but it looks like it is a good one.

    Awesome looking rifle -- And I really like the Arca rail.

    Using an Arca rail is the main reason I was considering the KRG Bravo.

    Which rail are you using?

    How is CCI worse then Eley or SK on your rifle?

    Their lube is JUNK. It will gum up your chamber, bolt and action. also leaves a film in your magazine lips.

    I have a B14R and have had issues extracting live rounds with both CCI and SK rifle Match. I don't know what chamber Bergara uses but it is tighter than the 10/22, Marlin model 60, and Savage FVSR that I have and shoot.

    Having said that, the Bergara is the first experience I have with "match" chambered 22LRs

    BTW, I also find CCI SV shoots pretty good out of all my rifles.

    Sorry but my neither of my Vudoo's will chamber SV smoothly. SV has tendency to hang up going into the chamber and bolt close becomes very tight. I also can see some lead shaving in the throat after just a very few rounds of SV.
    They are really meant to shoot and feed at their best with match ammo, especially Center-X. Both of mine are perfectly happy when you feed them Center-X, SK Long Range, Tenex or even Eley Club.

    Ok. I run a bit of ammo through in a year and in my experance the CCI is very slightly dirtier then Federal and SK/ Lapua. But the left over lube doesnt collect dirt like the SK.
    Eley has almost as much carbon but like you said the CCI lube is gummy after shot. I have not seen any degrading in a rifle specifically from CCI.
    I have a RimX here that actually shoot CCI sv better at 200 yards then Lapua Center X.
    My main use for Rim fire is PRS comps and ELR. So 50 yard is of little interest. But at 50 the Lapua is better.
    I would hesitate to simply write off a certain ammo as unfit for a high end rig. Or say that guys are wrecking them with "cheap" ammo. Now I do not know what the Vudoo chamber specs are and could be tighter then the Calfee 4.

    What distance was that shot at? 50yards?

    CCI SV will hold 1moa out to about 70m for me but open up rapidly after that due to inconsistent velocity.
    About 2moa at 100m and 4moa at 200m seems the norm.

    @Snuby642...Yep, mighty fine 5 shot group.

    I've done that a few times myself.
    Problem, it's not representative of the rest of the box.
    The question I have to ask is "What happened to the other 45?" :D

    Seriously, 5 shots is a random act of accuracy,
    especially when the rest of the target looks like an animal shelter, covered in strays.

    Show me a 6x5 at 50 yards with CCI SV, or a USBR Green monster with a score in the 240's
    or even a whole box at 100 yards, then y'er beginning to show what the cartridges can really do.
    A single 5 shot group? Doesn't come close to being a good example of consistent accuracy.


    I know, I'm an annoying old coot. ;)

    But if'n y'er gonna claim "all day long",
    y'er gonna have to offer greater numbers of shots, all on the same target.
    Not cherry picked one from here and one from there. :(


    Do you really expect predictable trajectories, when the cartridges look like these?

    Dents, dings, chips, irregular crimp lines, bullet material compressed down on to the brass,
    uneven nose to drive band transitions, tilted seating, asymmetric drive bands....that's just bulk 22lr....CCI SV.

    Not cherry picked one from here and one from there. :(


    Do you really expect predictable trajectories, when the cartridges look like these?

    Dents, dings, chips, irregular crimp lines, bullet material compressed down on to the brass,
    uneven nose to drive band transitions, tilted seating....that's just bulk 22lr....CCI SV.
    Like a hawk lol! The fun part for me is how that really expensive "stuff".... at 200. 😉 the lot of cci i have right now looks better then that "stuff". Oh ya the bulk lottery.

    Here are my results.
    I will say that at 100 and beyond the CCI doesn't hang in there with the match ammo from my experience, I try to use it for up close or plinking steel only.

    CR, it's like ya' know me. :D

    Z28, that's what I like to see.
    Not just a single group, but the whole box on one target. Well done. (y)

    Thanks -- good suggestions.

    Of course, I do not intend to shoot CCI SV exclusively. But I was hoping to have that option, since I have so much to it.

    I realize the Vudoo is built for better ammo, just unaware that it cannot shoot non-match ammo.
    What a lot of folks don't know about Vudoo is that they are not really a production rifle shop. I talk about this some in the review I did of the v-22 this year. They have "models" but most rifles are made to specific customer specs and not built as standard models to be sold later. As such, they can build with whatever chamber, barrel, stock, trigger, etc. that you want. They also have the knowledge to help you choose. If you want to optimize for CCI std, you can do so. Vudoo's house chamber, the Ravage, is optimized for the Lapua Center-X family but many customers order with chambers optimized for other stuff such as the Eley EPS. For what it is worth, the CCI std lots I have shoot fine out of the Ravage chambered Vudoo I have with only a few harder bolt closes. I suspect different lots of CCI are the reason some have an easier time than others feeding it into a Ravage chambered Vudoo as I really doubt there is much difference in the Vudoo's and CCI varies a lot from lot to lot. For my part, I shoot a lot of CCI Std and Eley CMP out of my Vudoo for practice and playing around while using lot selected Center-X in matches.

    Anyhow, you can get a chamber optimized for whatever you want in a Vudoo so it is not about whether a Vudoo will do the ammo you want but rather about choosing a chamber optimized for what you want.

    Here is what the CCI looks like at 50yds. As many have mentioned, it does not have good velocity consistency (ES's of 50+fps) and falls apart after that.

    Interesting indeed.

    But I would assume the Bergara's chamber is not nearly as tight as the Vudoo's -- Correct?
    There are a few things known about the Bergara chamber. Since the rifle has CIP stamped on the receiver, its chamber is made to CIP specifications. We know the diameter of the chamber and we know it's minimum length. Bergara may use a somewhat longer chamber, but how much longer is not known. CZ also follows CIP specifications and has a match chamber in several models -- the MTR, the LRP, and now the VPT (Varmint Precision Trainer). Other CZ rifles, also CIP, would have longer chambers to more easily accomodate a wider variety of ammo. Both Bergara and CZ have CIP spec bores, which are smaller in diameter than bores made to SAAMI specs.

    CIP bores such as those of Bergara are .212" at the lands (.220" at the grooves). SAAMI bores are .217" at the lands (.222" at the grooves). CCI SV ammo has a longer driving band than typical match ammos. In shorter chambers, this can make CCI SV ammo engage the rifling in tighter CIP bores more strongly, making them difficult to chamber or, if chambered, to extract live.

    What is not known is what chamber is used on the Vudoo repeater. (It's not the same as on the newer Vudoo V22S single shot BR barreled action.) From information that's been made public, the Vudoo chamber is designed by Mike Bush and is made for Lapua ammo, although it should shoot other match ammos without issue. (According to Mike Bush in a post on RFC in 2019, "The chamber is a match dimension chamber of my own design and exclusive to Vudoo. As many of you likely know, the Win 52D chamber is the shortest and tightest of all match chambers. Without the lead, the chamber measures .580 in length, the Vudoo chamber is .605 in length. There are many match chambers that are longer and looser than the Vudoo, but as a match chamber, the Vudoo has no issues extracting and ejecting loaded rounds." See RimfireCentral.com Forums - View Single Post - Will a Factory Anschutz shoot better than a Vudoo)

    Also not known is what bore dimensions the Vudoo barrels have.

    As shown in the bottom-most diagram below, chamber diameter is similar between the most common match chambers, with breech side diameter varying by less than 30 ten-thousanths of an inch. In fact the Win 52D chamber breech side diameter is larger than many others.

    Where the various match chambers differ is in length, whether they have any taper (smaller at the leade end), and leade angle. Both CIP and SAAMI have no chamber taper and a leade angle of 5 degrees; most custom match chambers have angles of no more than 2 degrees.

    Below are the CIP specifications. The SAAMI Match specs are next. Last is a commonly seen chart showing reamer specs for a variety of .22LR chambers (SAAMI are shown as 22LR Match and 22LR Sporting). Note that the measurement "C" in the reamer spec chart doesn't have the exact same dimension on the CIP diagram. It's equivalent would be length L3 (17.51mm) with the rim thickness of 1.09mm subtracted from it, giving 16.42mm (.646") as the "C" dimension.

    I'll apologize in advance if I've made any mistakes here.

    Very interesting. I told Vudoo I was planning to shoot CCI for practice and SK for matches until I could send it to Lapua and do a lot test. Wonder how my chamber will be cut?

    What distance was that shot at? 50yards?

    CCI SV will hold 1moa out to about 70m for me but open up rapidly after that due to inconsistent velocity.
    About 2moa at 100m and 4moa at 200m seems the norm.

    Yes sir, 50 yd my bad, that would be aproxamatly 1 moa.

    Point was not made well on my behalf.

    A Ruger 10/22 with a modest barrel upgrade and the cci sv is capable of moa groups with an old man shooting.

    Neither the gun, ammo or the shooter will win any reasonable matches.

    Now to the premier bolt guns and match ammo with scopes that cost more than the 129$ sale price of my Bushnell.

    I would expect much more than some have experienced.

    And on the subject of changing rimfire ammo.

    Any change should include strip cleaning the barrel and then reconditioning with about 20 shots.

    There is not much use shoving match ammo in a semi and also not much use shoving semi ammo in a match gun.

    Either way you are pissing money and shattering expectations.

    IMHO

    My measurements of CCI sv dont show it any longer then SK.
    You're right. CCI SV rounds and SK -- indeed all .22LR ammo -- are manufactured to conform to CIP and SAAMI specs. The overall length should be the same. There will be variation in dimensions between makes of ammo and individual rounds, especially with inexpensive, bulk ammos, but all .22LR ammo (with the exception of extraordinary rounds such as CCI Stingers, which have a longer case length) have a standard. See the diagram below. CIP dimensions are the same.

    Apparently what makes CCI SV ammo different from many others is the length of its driving band. This is confirmed by Brett Olin, then rimfire development engineer at CCI in Lewiston, Idaho, in a 2010 email reproduced here RimfireCentral.com Forums - View Single Post - 1712 and CCI - Hard to chamber - Need alternative or fix for SB Silhouette

    It's likely that the tighter CIP bores and shorter chambers together cause CCI SV to be harder to chamber in some rifles with match chambers, including Vudoo, Anschutz match rifles and some repeaters, and some Bergara among others, including some CZ match chambered rifles.

    Sorry I was not clear. I meant base to ogive length. I realize not all lots will be the same. I have been doing some testing regarding Length to Ogive relating to what ammo a rifle likes. The cci shoots simular to other ammo of the same length at 200 yards. Maybe its for nothing.. I just wonder things and have a hard time finding answers to rimfire questions and long range.Screenshot_20210210-093518_Excel.jpg

    Well not the cci sv I wanted but it was a good snag today.

    CRPS Shooter, I have also tried sorting by base-to-ogive measurement. I wasn't convinced that it was particularly fruitful in terms of results. Generally speaking, the less expensive the ammo, the greater the variety of sizes within a box. In better quality ammo, the majority of individual rounds fell into a few close lengths.

    Perhaps one of the peculiarities of CCI SV ammo is the average bullet diameter. About 15 years ago, Steve Boelter published The Rifleman's Guide to Rimfire Ammunition. Although it is now outdated in many respects, including the discontinuation of many of the ammos he compared, his data included bullet diameter measurements. While his methodolgy may not have been the most rigorous (Boelter selected ten random rounds from two boxes of each type of ammo compared and measured various aspects of the ammo), his data indicate that CCI SV bullet diameter is on average greater than most other ammos, even the no-longer-available Lapua Midas L and Master L ammos which were made to a larger diameter than Lapua Midas M and Master M varieties.

    I haven't measured any CCI SV ammo as I don't use it very often. Below is the measurement data for CCI SV from page 72 of Boelter's book. A wider than average bullet would add to chambering difficulty.

    So 3 different chambers that I am aware of, I think one more type out there but not familiar with it.

    Stock, Bentz and match.

    Three different expectations.
    IMHO

    Edit: I'm a Bentz fan.

    Snuby642, there are more than three different chambers. There are many different chambers that are generally referred to as "match chambers" and only some of them are identified in the reamer chart shown in an earlier post (#41). The Bentz chamber is often used on semi-auto rimfire rifles.
