I bought a new 14.5" middy upper not too long ago from a very well respected company. The first time I shot it, it shot horrible. I had no feeding or ejection problems but I was literally getting 3 foot groups while trying to sight it in at 50 yards.
I notified the company and they had me send it back so they could check it out. I got a email from them today stating that they were changing the barrel. They did not say what was wrong with the barrel or what they found that caused them to make that decision.
My question is is what can be so bad about a new barrel that would cause it shoot that way and the company decide to change it? Bad crown?
I was wondering if one of the more educated members here could give me some ideas why they would decide to re barrel it. Thanks!


". Examining the fired cartridges, they are "inflated" near the rim because the chamber is too large. Probably the reamer was off center when it was run in though it could be other things. You can put a cartridge in the chamber, put your pinkie on it and wobble it around a lot. If you have any fired cases on hand examine them, look for a slight bulge near the head. Doesn't take much to mess things up.
