Thread: tight closing the bolt

Looking back at it with fresh eyes after your statement it sounds like it was a combination of under-lubing and super hard / springy Winchester brass. Interesting.

I found quite a few problems making brass out of 270/30-06 to fit my 280 rem
one even blew the plastic bolt shroud off my tikkas bolt
now I just buy the proper headstamped stuff

almost put me off handloading
