The least expensive way to get it fixed will be to send it to Winchester. Have you tried a differant lot of ammo? It could be soft brass. We saw a lot of it when the WSM was first introduced.
Weatherby brass is as consistent as anything ever produced so it's unlikely I'm dealing with soft cases.
I agree there is little chance it's anything but an over-pressure situation. The question is, "Why?".
My thoughts leaned towards a throat out of spec but for some STUPID reason I never suspected a copper buildup. Obviously this used rifle might have been shot a fair amount & cleaned up to where it looked
to be unfired. A copper buildup in the barrel is something I should have checked. Thank you for reminding me to check the obvious!
