[QUOTE="Darryl Cassel, post: 23829, member: 34"] MM Every rifle cartridge/bullet combination has it's own accuracy range. For instance, at the 1000 yd matches in Williamsport, the accuracy range for a 30 cal 220 grSierra MK is 3000 to 3040 FPS. This seems to be the velocity most people strive for in thierr 300 Weatherbys and wild cat rifles. For the 240 gr Sierra MK---2850 to 3000 FPS seems to work for most at the 1000 yd range. That would be 2850 to 2900 FPS with the 9 twist. Please understand, these rifles have at least 30" barrels on them. For hunting, the speed is increased with large cases and longer barrels For LR hunting out of my 300 Tomahawk which has a 34" barrel and A 10 Twist, I push the 240 gr at 3200 FPS and it is unreal at yardages to 1800 yds. Just some added information to ponder. DC [img]images/icons/smile.gif[/img] [/QUOTE]
