Testing .308 Ammunition hand loads. Shooting 178 grain AMAX. What velocity will be best? Part 1.

[@mr_agave]

Still like the cerakote on that one. Miss my .308

[@RugerGundog]

Indeed. That rifle you built was a beauty.

41.5 - 41.8 of IMR4064 in small rifle primer brass behind a SMK175 will give you 2400fps, single digit SD, and beautiful bug holes out of an 18” barrel.

I'm using standard large rifle cci primers. I do think I will try a few more grains to try and bump my velocity a 100fps or so. Thanks for chiming in.

178s + 43.5 grains of varget over fed gmm works in every 308 I've tested it in. 26" barrel at 2705 currently

[@RugerGundog]

Thanks for the load data. I do want to try varget. I've got 3lb imr to work through.

Reloader 16 supposed to be great for heavy bullets in 6.5 creedmor. 20" 308 only got 2340fps with 168smk. Dissapointing..feel your pain. Not notable groups either

[@RugerGundog]

Thanks for the input. I guess it's part of the "fun" sorting this stuff.

[@lmbear]

Way too slow. Doesn't matter what type of accuracy you are getting thus far. You should be running much faster than that. You might as well be shooting a 300 Savage..

[@RugerGundog]

I'm going to run another short session with both these loads as well as one up to 42g of powder...suspect get me at smidgen over 2400 fps. Those loads were both approx 50fps below what land book suggested.
