[QUOTE="Overkill338, post: 1660592, member: 110473"] Here is a test where they took a 300 wm down in several steps from 24 to 16. 20" was 140 fps slower, 16 was 300 fps slower. I'm actually thinking about cutting my M77 MKII down to 20"-22" to stiffen the barrel up. In this test, it actually gained velocity when going from 22 to 21 inches. I guess that was the point where the bullets friction evened out?
