[QUOTE="Alexander D Jolley, post: 1638877, member: 110200"] I am using norma brass for my .300 norma mag, with hornady 220 eld-x bullets and H1000 powder out of a 22" Proof Research carbon fiber barrel. I have been using 84.2 grains and getting 2864 fps on my five round group. How much of a difference in fps do you think a longer barrel would make? I would like to get over 2950 fps but I am not sure how much my shorter barrel is effecting the velocity. [/QUOTE]
