[QUOTE="theirontexan, post: 1150042, member: 93829"] I recently had a 6.5-06 AI built by pac-nor. When loading for this rifle, I ran into the fact that it was showing pressure signs far before I would imagine it should. I was half a grain under the suggested max for the non ackley improved version of the case, and I had a flattened primer, and ejector markings on the back of the casing and the primer was formed around the firing pin. The only thing I would consider different from any other cartridge I've loaded is that the throat on this rifle is really short. I loaded it with the bullet touching the lands, and the OAL was 3.255 as opposed to nosler's 3.440 with a 130 grain accubond. Also, would it be possible that I am running into high pressure because the bullets are so heavy for caliber as opposed to a 25-06 or a .270? I've never reloaded for a rifle that showed pressure signs this early, and it bothers me to a rather high degree. I'm loading IMR4350, do I need to change powder? I'm lost, and I'm especially worried because I want to bump up to a 140 grain bullet (got the accubonds at the local gunshop, it was what they had, and I wanted to go shoot my new gun.) But if I do that, will it make my pressure issue worse? [/QUOTE]
