I understand barrel twist, i think. My remington 700 has a 1:10 and so does my browning x-bolt. I believe this means the bullet would make one full rotation every 10 inches...How does this affect accuracy and bullet weight? I will be reloading for both rifles and am starting to try and determine which bullets to try first. I know there are no guarentees for accuracy as every rifle is different but just trying to understand this twist. The remington 700 is a 3006 with 22 inch barrel (mountain rifle) the browning is a 300WSM with a 23inch barrel. My goal with both rifles is accuracy out to 500 yards (which 1.5MOA would be minimum needed accuracy). Both would be used for deer with the possibility for ELK/Moose but for now are very unlikely until next year.
