[QUOTE="Seabeeken, post: 2726630, member: 68015"] Have you tried more or less neck tension or even a crimp or a magnum primer? I had similar results with ball powders. IME, they can vary speeds like that but give me very good groups. I've found Hunter an excellent powder. Recently I experimented with my 6XC and 69 gr AH. I could not find a single single base stick powder that it liked. I was shocked. I went to ball powders and things improved as far as groups but ES wasn't that great. I tried other ball powders and found TAC and A2520 shot single hole groups and ES 10-15. With that said, I was working with my 243AI several years ago with H-414 and got pressure spikes at several charge weights and then the next increment would show normal. Haven't seen that before or since. Probably not much help with this but ball powders can be strange but I often get excellent accuracy. [/QUOTE]
