So long story short, bought an RPR in 6 Creed last year. Factory barrel made really small groupings. Figured I would buy an aftermarket barrel to get even better groups. Did load testing with new barrel. Used 4 different bullets and did load testing for all. Nothing, wouldn't group better than MOA at 100. Had the barrel looked at by competent Smith and he was puzzled. Gave him whole gun and he did load testing and same results, nothing better than MOA. Put the stock barrel back on and sub moa groupings again. Called barrel maker. Sent in barrel, they said nothing wrong with it. Came back to me and same story. Well, I will never be using that manufacturer again. Some companies have good CS, and some don't.
