Unclenick - That's all interesting stuff and good to know.
I've has a Contender for a while but am just now finding out about frame stretch.
I missed out on the IHMSA craze of the 80s so I haven't had the opportunity to compare notes with other Contender guys - Other than on the internet.
Yeah - With high enough pressures, even if the .30/30 AI cases clung to the chamber walls, the weak point would be the web.
If Ackley pursued destructive testing and continued firing the gun with tthe lug free bolt til it reached the breaking point, the case head would separate, eventually.
Don't cha think?
So I'll be looking for case stretch
My mission is to come up with an accurate / reliable deer load using lead free projectiles for hunting in Calif. (Mandatory lead free here)
This isn't the first thread I've read where someone mentioned having used 41 gr of LVR in the .30-30 AI with 150 gr bullets.
I stopped at 38.5 gr
