Yes, thank's.
I've got a source for the brass ones right now.
I can't even imagine doing this with steel ones, not to mention, in my opinion it's just not "right".hehe
I can't stand steel cases.
I'm going to stock up on these brass ones, but, for obvious reasons, a lifetime supply of 4-bore cases is kind of low in number.hehe
If I shot it too much I might end up like Selous was.hehe
