Can anyone explain this to me. I have a gun that shoots 5 shots into about 1/2" after cleaning, then the groups open up to about 3". When I clean, it has very little copper in the barrel.
Are these shots fired consecutively? In other words, does this happen when you fire more than 5 shots in one sitting, and have you fired 5 shots on a different day with a fouled bore?.......Rich
I was thinking that you may have had a bedding/barrel heating problem, but if it repeats itself with a cold/fouled bore, that is curious? So the first five shots out of the fouled bore do not group either. Is that correct?
Yes, you are correct. When I shoot I wait at least 10 min between shots. The barrel is not even warm for the next shot. I do think I am having some bedding issues. What gets me is that the first 5 shots from a squeaky clean bore are great. It's opposite from what you normally see.
