I'm preparing to develop a load for a 14 inch Contender in 222 Rem. I know that when firing rifle cartridges in handgun-length barrels, faster powders generally give more uniform velocities. But does bullet weight have much effect on getting consistent velocity? I really don't have a specific purpose for this barrel, i.e., varmint hunting, punching paper, etc. I just want to work up an accurate load. By the way, the twist rate is 1:12, if that matters. These are the 22 bullets I have on hand: Speer 50 grain TNT and 45 gr soft point; Sierra 40 & 45 grain hornet and 63 grain semi-pointed; Hornady 52 grain A-Max. I plan on using H4198 or AA2015BR. Thanks for any input you might have.
