[QUOTE="Meister, post: 99739, member: 4118"] Unless your sound suppressor uses wipes, it should boost your speed. Mine boosts my 308 about 30 fps. I have 2 223 rems and 1 has a 24" 1 1/4 round barrel and a 1-7 twist for the long shots(heavy mother). My other is a semi auto registered SBR with a 10.5" barrel and a suppressor. It adds 10 Fps to the velocity. For most long range purposes a 20" will do fust fine. you can change your powder to achieve closer to proper speed in a shorter barrel. [/QUOTE]
