[QUOTE="Bang4theBuck, post: 3049725, member: 73596"] I have shortened the barrel on numerous rifles recently and have gained back most if not all of the velocity losses by switching those rifles to copper monos. Three things contribute: 1. Less engraving pressure makes more velocity. 2. Less weight needed in good quality monos that perform as designed. 3. Because there is less engraving pressure, you can typically use a faster burning powder without as steep of an initial pressure curve. Faster burning cuts down the flame-thrower and accelerates the bullet in a shorter tube. Its worked for me in numerous cartridges [/QUOTE]
