I am working on a build and have found in researching that a lot of times people are have ejections issues when using this combination of action and ammo. I also saw something along the lines of modifying the extractor a little bit to get things to work. Does anyone here have any experience with this situation? Any ideas, experiences or comments would be appreciated. Just a thought, but would a controlled round bolt head do anything to make this work better? Thanks, Gristlehead
