One hole loads for your Savage 12 LPRV 1:9
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.

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.

...Sounds like you need to bump the powder... ;).
Re: One hole loads for your Savage 12 LPRV 1:9
I am gonna have to try that. Haven't had pressure signs. Wasn't trying to push it to much. I hope my wife catches a hint or two and gets me a chrony for xmas, so I can really see where I am at with some of these loads. If not it won't be until I finish the .260AI in January. Is that pretty much a rule of thumb if you have two really tight and an odd flyer?

Does anyone have a tried and true 75 Amax load in a savage 12 1:9 twist?
Re: One hole loads for your Savage 12 LPRV 1:9
Only in my 223 AI 1:9 twist factory Savage barrel. 3150 fps with H4895.

That helped some T.S. Gonna see what it does at longer ranges. Really close. Close enough I might try some different powders. Maybe I'll order some VV140 or 540. Can't find any here in OKC unless someone has a suggestion. HandH doesn't have either.
Picked up some of the 75 BTHPs from Hornady (only $14 bucks and change at Gene Sears, worth the try).
My .260AI will be done soon enough. I just want a super consistent cartridge for my wife to stretch out to 600 with and build some confidence to the best degree we can with that rifle. Appreciate all your help guys
