Anyone have any experience with the 223 and 69gr TMK combo? Sierra recommends a 1 in 10 or faster and looking to shoot this in a 1 in 9. What powders? Any info appreciated
A long time, when I was shooting an AR15 Hbar 1/7 twist .223 in matches I used to use AA2230 for the Sierra 69 gr MK with good results. I believe I went to H335 for the heavier Sierra 80 gr MK.Awesome, I think I will give them a try. I have some varget, AR comp, and BL-C2 to try them with. Thanks for the info everyone
I currently shoot the projectile in my .224 Valkyrie AR, and my Mossberg MVP Predator in .224 Valkyrie. The AR is a 1-6.5 twist, and with four different powders, I'm getting sub moa. The bolt action is a 1-7 and loves the 77gr TMK's but shoots the 69 gr excellent!Anyone have any experience with the 223 and 69gr TMK combo?
