I'm finally at a point I can try working up some loads for my 12" GB. I was able to obtain a few hundred 129 ABLRs for a great price.
Here is what I have to work with. Loads will be chrono'd with a Magnetospeed.
Brass: I have a variety to choose from. Once fired Hornady, Federal, PPU/Wolf. I also have new Lapua but this will be for hunting and I'd hate to lose that. I'm also considering pulling Wolf steel and using those cases.
Powder: I need temp stable. It will be 70's and 80's here during development but 20's and 30's during use. I have 8208 (pressure spikes understood), AR-Comp, Lvr, AA2495, 780 Supreme. I also have IMR 4895 and Varget but I don't think the velocity will be there with those.
Primers: CCI 41, CCI 450, WSR.
Looking for suggestions with these combo's.
