Savage 12 LPRV 1:9 twist .223 proven loads

[basshusker]

Here are some proven loads for you guys to try.

Savage 12 LPRV 1:9 twist in a McMillan A2 stock with aluminum bedding block. The OAL is to the lands for my chamber. Should be within a few thousandths for someone with the same model rifle. (I used the Hornady tool to find it. Remember each bullet is different).

These are all with once fired LC 09 brass. I have had good luck with it. Better than with the RP or Winchester. Oddly the Fiocchi GFL brass (50 pieces)I have had good luck with also). No pressure signs.

Nosler BT 55g #39526 (not the 250 round Varmint pack ones, I think they are different)/Varget 24.9 OAL 2.332
Pretty foregiving with Varget. I can shoot from 24.6 to 25.9 and still be within 1/2"- One hole at 24.9 though.

Sierra 69 BTHP MK #1380- OAL 2.332 (2.342 to lands). 26.0 Varget (someone else on another forum had the exact same results on another forum, can't remember the name but his lands measurements were within 0.002 of mine. One hole (not a cloverleaf, one hole).

75 A-max's. Using RL15 and Varget I can't seem to get these dialed in. I keep gettin 2 about 1 hole then a flyer from 1/2 to 2" off. They are not keyholing..

so that is positive. Gonna try some viht n140 when I can get some. Recommended from Walt at Berger for the 70s and 73s.

Speaking of which, my initial OCW testing on those is promising. Using Varget, and checking POI I shot 18 rounds inside a quarter with 3 different Varget charges from 24.0, 24.5, and 25.0 (Berger says 24.8 is max, so watch for pressure signs) on both the 9 shots for the 70s and the 9 shots for the 73s. Each of those groups were touching each other (25.0 with the 73s pushed it outside of a nickel).

Gonna do 24.3, 24.5, and 24.7 now to validate and then mess with the lengths. Used 2.340 for the 70 and 2.375 for the 73 which put it at the lands.

Also, I have had better luck with the Nosler CC 77grains then the Amax's oddly enough. I have those shooting 5/16th without playing around with OAL. 24.8 Varget. The bergers both have better Ballistic Coefficients thought so I am gonna just use the rest of the box for foulers.

Email me at jjkuchar at gmail and I can shoot the excel spreadsheet I am using.

Hope this help some people.

Re: Savage 12 LPRV 1:9 twist .223 proven loads

When I get a chrony for xmas I will add that info

Ballistic coefficients
Nos 55g BT (orange) .267BC/.157 sect density
Sierra 69 BTHP 1380 .317BC/.196 sect. dens.
Berger 70 VLD .371BC
Berger 73 BTHP Target Match .343BC
Hornady A-max 75 .435BC/.214SD
Nosler Custom Comp BTHP 77g only .340/219sect density

Looking at this, if your rifle can shoot 'em, -Amax, Berger 70, Berger 73, then Sierra 69s are probably the way to go.
The 69s are proven and will give you better velocity range then the a-max would be my guess. Just gotta see what the 70 VLDs can do.

Re: Savage 12 LPRV 1:9 twist .223 proven loads

Hi Justin,
The two powders you list are quite popular as is Viht N140 for these two bullets in the 0.223 Rem. Load data was generated using Quick Load a 24 inch barrel a COAL (cartridge over all length) of 2.260 inches and your COAL and velocity could be a little different.
AS WITH ALL RELOADING APPROACH THE MAXIMUM LOADS WITH CAUTION AS ALL RIFLES AND RELOADING TECHNIQUES WILL BE DIFFERENT. If YOU CHANGE ANY OF YOUR COMPONENTS; THIS INCLUDES DIFFERENT POWDER LOT NUMBERS; YOU MUST REFIGURE YOUR LOADS BY STARTING WITH THE MINIMUM LOAD.

If we can be of any additional help feel free to contact us.
Thanks for your interest and have a great day.

Re: Savage 12 LPRV 1:9 twist .223 proven loads

Hope this helps some people. I know I looked all over the place and found bits and pieces, but often times there was one or two factors that were different and didn't line up with my setup, i.e. 1:8 twist, etc.

I am gonna use Walts advice and try the viht n140. One thing I have noticed when using different brass, is I seem to get the best load when it the powder is just compressed. I will have to do some more research on that as a comparison to OAL. The OCW(Optimal Charge Weight-google it, good read) method rather than the ladder method seems to save some time with load development also. I know that will be my starting point for my .260AI when it is finished. I am excited about slapping that new Vortex Razor on and seeing what it can do.

Re: Savage 12 LPRV 1:9 twist .223 proven loads

hey Basshusker I have tried IMR 4007 with a 75g BVLD and got them to shoot a .308 group.was useing 25.5g with the bullet in the lands.even got a 77g NCC to shoot one hole with the same powder useing 25.0g.just thought that you might wanted to try a different powder.its working for me.and JMO

Re: Savage 12 LPRV 1:9 twist .223 proven loads

In my Savage 12, 26.0 of Varget with a 69gr SMK @ 2.260 works well. Can't get the 75gr AMAXs to shoot that well, either.

I also load a Nosler 50gr (orange tipped 250ct bulk pack) with 25.5 of AA2230 and it shoots good. Just as good out to 300 in low wind conditions as the 69gr SMK.

Re: Savage 12 LPRV 1:9 twist .223 proven loads

Thanks for the tip on the powder. I really like the 55 nosler BTs. I don't know about the 250 varmint pack ones though. They don't shoot as well. The number and picture are different. I ended up trading with a coworker. They work well in his AR. I use the same varget load as the smk's just different OAL.

I am using the federal small rifle match primers (GM205 I think).

I am gonna work some more on the 70 bergers and 75 amax's this week to shoot all next week. Taking some leave finally.

Re: Savage 12 LPRV 1:9 twist .223 proven loads

Unfortunately can't find any N140 here. Anyone tried the N140 or any of the viht stuff. How does it meter and how well does it hold up to temp variations? Thanks in advance

Re: Savage 12 LPRV 1:9 twist .223 proven loads

Lots of good info in here Thanks, I have always had really good luck with Win 748 in the 223, mostly used the lighter bullets though, would like to start shooting some of the heavier bullets.

Re: Savage 12 LPRV 1:9 twist .223 proven loads

Got the load chrony'd with Alpha Master in my wife's Savage 12 LRPV w/factory 26" barrel w/ 1:9 twist in a McMillan A2 stock off the bipod and rear sand bag.
23.8 g XBR over BR4 primer
New Nosler brass with nothing done to prep it.
75g A-MAX

2901 average. 32 ES. 8 SD. over 25 shots.

No pressure signs. I haven't chronied my a-max 25.6 varget load but iirc, backwards from my mil to 600 put me at 2715fps.

Pretty promising stuff. Still pretty windy out but 5 shot groups were in the .2s to .4s. Could have been mostly two's and teens if I had a sled or front rest instead of the bi-pod.

Good stuff.
Justin

Re: Savage 12 LPRV 1:9 twist .223 proven loads

I have been working with a LRPV 223 1-9 for a year. I have had great luck with it in score and group out to 300 yards. which is as far as I have tried it. I didn't have much luck with Varget, and really don't like the powder as it throws terible for me in both my measures. But I have had great results with XBR 8208 and 70 grain Bergers, runnin 2952 av. with sd's in the high teens. I have found about .020 into the lands seem to be best for my gun. .010 off is as far as I went, but the gun consitantly shoots in the .3's will do .2's when I get my sh## right, but I have had real good luck with 8208 in 308 win loads also. Don't get me wrong I have shot it in the low 4's but I know it's me and not the load. I would like to try the 73 grain Bergers but will start with 8208 when I do, I think it is a better 223 powder than it is in my 6ppc unlimited gun!
