A buddie and I built identical rifles excepth. His has a 23'' barrel and mine has a 26 He found a good load and I tried it in my rifle. Both rifles crony the same volicty. I am going to try more power but limited as it is with in 1.0 gr of being a compressed load. Question is. Also want to try another powder. Do I need to go to a faster or slower powder to gain move volictiy? I went with a longer barrel to go a little faster. Thanks for your replys!
