I went to Sportsmans Warehouse today to get a few things and the 162g AMAX was on the list for the STW. Come to find out, they say they require a 1 in 8 twist. I did not know that. There advertised b.c. is .625 though. So just to be safe, I bought the SST version with a b.c. of .550 Could you shoot the AMAX out of the STW? I'm not exactly sure what twist mine is, its gotta be a 1 in 9 or 10. Winchester model 70. Well, I will be doing 2 more ladder tests. 1 with the STW and the 162g SST, and another with my 300 RUM and the 220g SMK. I will be using H-1000 and IMR-7828. Will post results.
