Re: Velocity for a 300 RUM factory cartridge with 180 gr cor-lokt??
I know that everyone has a different tolerance for recoil, and I'm used to shooting big bore rifles. But, I would agree with your findings about the recoil from a 300 ultra that has had a brake installed. Not bad at all, don't be reluctant to shoot it. The velocity of the 180 core-lockt is roughly around 3250 fps at the muzzle. You've got yourself a great shooting rifle.
Shoot that fine firearm with confidence,
