[QUOTE="Mrhounddog, post: 1641465, member: 75135"] Hey Ninja, A few questions: - How many times have you shot this rifle...total? - Have you thoroughly cleaned the chamber, specifically the neck and throat area? - Have you checked the neck thickness on the brass you are using? What you are describing sounds like pressure differences between shots, which could be related to inconsistent bullet release. The neck tension has to be the same for all shots...obviously. If one round has a thicker neck, with increased tension before release, then the pressure is higher and it will not group. Excess carbon in the neck/throat area can do this too. Of course, you have to be reloading very consistently to eliminate that as a variable. All of this to give you one or two more things to look at. Hat tip to Kiwi Nate for accuracy stuff. [/QUOTE]
