I bought 1100 SMK's for my 7mm rem with the 26", 9.25 barrel. Then I read Sierra's warning about "8 twist or faster". I ran this bullet through the Miller twist rule calc. and can get it to the 1.5 "comfortable zone" at 2800fps, 70 deg temp @500ft elev. but that means max loads. I also have 500 Berger 180gn hunting bullets, and they recommend a 1/9 twist barrel, but running the same parameters except for bullet length I get a stability factor of 1.36. Having zero experience, Is it safe to shoot these? Do I sell/trade them all? do I file the tips to shorten them up to get to 1.5+? What would you do?
