Thread: Can I fire form with an action and dies like this I'm

Genuine question, no idea if its possible or safe

Not all chambers are created equal

Fire formed in dies or fired cases from another rifle sized sizes in the dies you have.
Measure very accurately a number of cases and get the specs for the chamber reamer you want to make
Allowing for the bore diameter and bullet and case mouth thickness and diameter to be sure the case will let the bullet go
