I'm using a hard walnut tumbler media and Winchester brass.
After tumbling the media about 1/4 of the brass has a bead of media stuck in the primer hole which I have to flick out with a paperclip or whatever.
I thought about widening the flash hole a fraction so the media doesn't get stuck as easily.
Is this the way to go? Any problems with doing it?
How wide can/should I go too?
