Re: The first wildcats to cross my muzzle.
I had the bedding issue on my .22-250. It would alternate POI between the 2nd and 5th shots. Ends up, the front left and rear right corners of the pillars were higher than the rest. The action was not sitting flush or in a repeatable fashion. My uncle rebedded it for me, and now it devours 50 to < 60 gr bullets with about 1/2 MOA average. I have never fired it at 500 m, but both my brothers have with sub MOA groups. I look for similar findings with all my other factory rifles now. Hope this helps.
