Recently purchased a Pro hunter frame, and now in the market for a barrel. I'm planner to purchase my first rifle barrel im 7mm-08. My question, what kind of velocity increase should I experience with the Pro Hunter 28 inch barrel? Most factory published velocities with a 140 grain bullet are around 2860 fps with a 24 inch barrel. Just courious what 4 more inches of barrel will produce. Any insite on this would be apprieciated...
