Well I think we found the Problem took to a gunsmith he had a I guess you would call it a gage rod I not sure he started feeding it down the end of the barrel and in about 4” it got tight push through that in a few more inches no problem pulled it back hit obstruction measured to end of barrel...
I feel like we have eliminated everything but chamber and barrel used a different scope bore sight several different times took muzzle brake off different bullets my gun is same as my brother’s problem gun and mine shoots everything his won’t from target I posted it looks like bullet is coming...
Ok gentlemen we went out and shot problem gun adj brass, cci 250 m primers, 60gr 570, 156 Bergers shot # 5 I seen two ground after bullet went through target 3 feet right of target and about one foot left of target.
