Scatter, what brand of brass was that?
OIC Winchester.
OIC Winchester.
not yet. will be next week some time before I can get back to the bench to pull it.Recently I was in the process of loading some NEW Winchester brass 300 Mag ammo for a friend and was having trouble getting the tolerance which I like. I annealed some of the cases and resized them to see if they would react better. What I found in some of the brass was a crack, just from sizing, that appears just as your case looks. Inspecting it with a punch I found that the brass was in two layers and they could be separated.
Have you pulled the bullet?
I use lots of Winnie brass--not because I like but because it was some of the only stuff I could find. My Winnie 44 mag cases seem to last forever--but in some bottleneck cartridges the cases can be suspect. In particular, the turning (or whatever it is they do when they make them) often has vertical chatter in the ID of the case neck, so I generally will run them through the sizer a couple of times (just enough to get the expander past the shoulder) even when brand new to smooth that down. I end up sometimes having to work the necks in the same way I would if I were necking down from a bigger caliber.Recently I was in the process of loading some NEW Winchester brass 300 Mag ammo for a friend and was having trouble getting the tolerance which I like.
