Cracks in the brass

[Dale Gribble]

I'd recommend anealing the necks on the rest of the brass before you reload it again. There are some online vids around on how to do that. Rifle brass can get brittle after resizing. Some military rifle chambers are "loose" and the brass is worked harder during firing and resizing.

Would neck sizing only help also in a situation like this, assuming you only use the brass in this one gun?
