[QUOTE="rost495, post: 37262, member: 1768"] Dakor From real life experience in 223 rifles I gain 50-75 fps with a 3 groove vs 4 groove. You have to load differently for each barrel and the end result is if I was getting 2750 safely in a 3 groove with 90s, I could only safely get to 2650-2675 on average with 4 groove barrels. FWIW, Jeff [/QUOTE]
