I recently bought a Henry Big Boy carbine in 44 mag, I'm also a reloader. Going through used brass, I noted there were odd crease-like "stretch marks" running horizontally across the brass after being shot form the rifle. They're really pronounced and don't come our after resizing. I'm sure it won't take long before it ruins the brass from stressing it like that. Cleaning the rifle today, I decided to have a look at the chamber and saw this: The chamber is really poorly machined and you can clearly see where it is not smooth. The brass is expanding to fill those deep grooves you can see. Being my first Henry, and my first lever action, I don't know if this is normal. Can any of you Henry owners have a look at your chamber and tell me if they're all machined this way, or if I need to reach out to Henry to see if I can get this fixed?
