[QUOTE="FEENIX, post: 2166907, member: 14204"] 165 LRAB requires a minimum of 1:8.5" twist. As I noted in #2, the twist rate is for stabilization, not velocity. For instance, if your current rifle has a 1:10" 24" barrel and you re-barreled it with 1:8.5" and 24", you will more than likely not gain velocity but will be able to stabilize the 165 LRAB. However, if your barrel length is longer, you will gain velocity ~25 FPS +/- per inch but YMMV. I have a .270 AI with a 30" 1:8" barrel propelling the 175 Matrix VLD at 2993 FPS with H4831SC. Others are claiming ~100 FPS more with RL-26. [/QUOTE]
