My favourite deer gun is my Ruger M77 compact in 7mm-08. The barrel is only 16.5" long, swings fast and very accurate shooter, but my velocities are about 150 fps slower than a friend's 7-08 with a 22" barrel. Understandably so, but does anyone have an idea as to how to optimize the short barrel's velocity. I shoot Hornady 139 gr. behind 45 grains of IMR4350 powder, the bullets are seated 0.025" back of the lands. Would going to a faster powder such as Varget and decreasing my spacing to say 0.015" be a viable solution?
