Brand new never used. Mounted once, but never fired. 2650 shipped

Mount is available and same condition. It’s the SPUHR QDP-4002 which is 1.5” height for use with clip on NV or thermals. 390 shipped

I’m gonna post a few quick times immediately with photos so as not to bump the post (if someone knows a easy way for a technologically dumb guy to reduce the file size of new iPhone photos I’d appreciate any tips. It’s a great camera but files are too large).

7 saum

I hear ya! It’s supposed to be a long range bullet capable of expanding down to 1300 fps, but being bonded, hold up at speed. But ya need to be able to get them to group if you want to make hits a long range. I was disappointed the Partitions didn’t group, they are a consistent 3/4” grouper in my win mag. I need to jump test the 200 AB, it, like the ABLR groups around 1”, but I haven’t jump tested it yet. I tried 175 custom coms and still just under an inch. My SD’s are single digit most of the time, so it’s not that.
Definetly got better results with a big jump think this is .070 off (roughly). I know it’s only 3 shots. But if I can replicate it multiple times I’ll be happy with it.
I had a couple others that were stellar until I had a flyer (it was me)
Need to clean barrel and retest a couple loads and I’ll be done I hope.

MTG wakes up to the fact, taxes are nothing but legalized theft

this is the 1st basic truth of taxation. you,or the bank,don't own it. the gov does. don't pay,they will take it. resist that and they will be happy to kill you. income tax is different. they take the $s before you even have a chance to not pay. they'd have to kill too many people if paying was done after you got the $s first. the tax code is made so complex that anybody with anything but a W-2 can't understand it and will always break some law that even CPAs don't know about. also,creates the $300/hr CPA crowd that many are forced to use. i do despite my simple and limited income. keeps somebody between me and the IRS that has a vested interest in knowing and following the rules.
of course the bottom line on all taxes is the lack of representation before they are levied. our "representatives" are all corrupt parts of the brute force system which we pay for. does anyone really believe that there is any substantive difference between the USA,the USSR,Nazi Germany? China is just ahead of the curve but palantir will help close the gap.
Shit, as a farmer, I get the money and then come mar 1st I send a yuge check to irs(state and fed). Thats the real punishment, having to write those mfers a check for 15-25k.

Barrel length and velocity extreme spread.

Well if you really want to see the difference the simple way is to load the same case over & over the same way with a subsonic recipe. I did this many years ago and found shorter barrels most always have a lower ES/SD than a longer barrel. Why? Not sure but guessing the added friction points could be higher in the longer. This showed up more when I went from using a .309 cast vs a .314 cast sized back to .313 in a 308win. One of the reasons I went to 16.5" tubes as once past 350yds a 10fps change starts making huge changes, depending target size. Past 550 on a small target and a 10fps change is a very quick miss.

Subsonics would not help in measuring this other than showing the effects when using subsonics. So yes a longer barrel in that case may actually increase the ES if you have already burned all your powder by 16”. Again in theory.

Wow black hills cheaping out with the hornagay bullets. Lame.

Just throw 77gr TMKs in there and send it.
Meh, if my recent testing and dealings with Sierra are any indication, hornady might be better. Don't waste your time with 95smk .22 or 7mm 183smk. Junk ass bullets that vary .030" oal or thin jacketed they come apart. Hard pass

@RAVAGE88 great idea placing the mag blocker as far rear as possible.
I considered this but didn’t know if pressure on the DBM would have any influence on accuracy.

One other thing to consider, and likely this is accomplished by the 3 different lengths of mag blockers you’ll offer.
Lots folks are using 3d printed mag extensions which are wider all around and will interfere with mag blocker unless given enough space. I thought there was something mentioned a few posts back that your blocker will interface via ARCA. Assuming that’s the case, the 1.5” will allow for clearance of the aforementioned.

Good stuff. Love the concept!

I don't know if this helps anyone.. but it might.


FWIW...Ogive OAL measured with a Hornady Bullet Comparator.

Blue Bullet , PSA / AAC 77gr OTM ( current production lot ) Pulled Bullet only Ogive OAL... .606".... actual OAL of bullet... .9825"
Green Bullet , Black Arc 77gr Horn. ( just received ) ......... Pulled Bullet only Ogive OAL.... .6045"...actual OAL of bullet... .988"
Red Bullet, BHA D556N9 ( current production lot ) ........... Pulled Bullet only Ogive OAL.... .607".....actual OAL of bullet... .987"
Pink Bullet, IMI 262... 77gr SMK ( Brown Box ) ............... Pulled Bullet only Ogive OAL.... .608".....actual OAL of bullet... .995"
Orange Bullet, BHA Mk262 Mod 1-C, 77gr SMK................ Pulled Bullet only Ogive OAL.... .6035"...actual OAL of bullet... .982"

BTW, Current Production IMI 77gr Razorcore... did not have a cannalure..... Pulled Bullet only Ogive OAL.... .595"....actual OAL of bullet.... .9785"

FWIW... I have no idea how much "margin" for error there is on cannalure or Bullet ogive placement, or the actual bullet OAL... but the alledged Hornady 77gr OTM, certainly has a narrower cannalure width, compared to the 77gr SMK

"Back Yard" testing with 24hr soaked, dripping wet newspaper, while not perfect... can be enlightening.

Having a burn pile helps getting rid of the soggy newspaper, Lol

I used to do a crap load of it , prior to Ballistic Gel / the internet being available.

What I am saying... is it was better then nothing.

One surprising "test", was comparing .357 Rem. 125gr SJHP to a 9MM Winc. 127gr +P+... both fired from a 2 1/2" Ruger SP101.

They both had very similar muzzle velocities, and bullet weights.... but the Rem. Scalloped Jacketed made a FAR more impressive wound cavity.

What that showed , was bullet design mattered.

While I wouldn't want to be shot with either load... the .357 bullet Scalloped but was going to mess some one up far more than the Winc. 127gr +P+.

Both penetrated the same... but since you could "peel" away the inches of newsprint, the difference was dramatic.

Soggy Newspaper was good enough to see which rounds could lose their jackets, or if the HP would clog up repeatedly.

We did a crap load of rifle rounds as well... all the way from .458 Lott - .223.

At the time, it was all we had.

It may not be as repeatable as modern ballistic gel.... but it sure showed us young men a lot.
