Hi, I recently installed a new barrel on my Stevens model 200. It is a 7mm chambered by one of the better gunsmiths. I used to have a McGowan barrel on the rifle and it shot great.
After installing barrel on action in started load development . Accuracy is OK but not great. The main problem I have is after shooting the brass will not resize without really forcing it into the full length sizing die. When I do this it is so tight the brass forms almost another belt on the case.
I have checked my die it works fine, it only does this on brass from this barrel
I tried both new and once fired brass
I have no sign of excessive pressure
Bolt closes on go gauge, doesn't close on no go gauge.
Does anyone have any idea what I could be doing wrong? I have about 800$ into this barrel, and don't want to send it back if I'm doing something wrong.
