Re: Horn 178 Amax will it work in a 308 w/12 twist?
Thank you for your answers. I fired a 3 shot group this morning and got a tad less than .500, so in FL in a cool 45 degrees and prob 40% humidity it will stabilize, at least it did once.
I'm cooking up some long range target rounds to play with at 700 plus yards and don't want anything that is going to be just marginally stable.
I'll stick with Sierras 175 MK's for now, which by the way over 44 grs varget with a cci br primer is shooting very well. I'll chrono it later this afternoon. 308
