[QUOTE="Fiftydriver, post: 132770, member: 10"] Did you shoot them over a chrono, it sounds like your running some higher presures as well. I have heard this with the Nosler cases that their internal capacity is smaller then say a Rem RUM case. That bolt lift tightness would make me think that. At the top of the bolt stroke is where the mechanical extractor cam goes into effect. Do you need to give the bolt a slight pop to get it to go this last little bit and then the bolt comes back easily, I would check your velocities and see what they are saying with these loads. On another note, that extractor pulling out would have me a bit worried. When Sako extractor is properly fitted to a bolt, the more pressure back on the bolt should pull the extractor down into the bolt, not out of the bolt. I would look into this as well, that is not right for some reason. Kirby Allen(50) [/QUOTE]
