I'll try that as well. I love simple and practical solutions using items that wouldn't otherwise be used for such an application. Thanks.

Yep, that's the tumbler I'm using. I guess when I have it running, I should begin to add more media until it appears that the media and the brass are rolling over at it's quickest pace? That sounds easy enough. I have it running right now, let me do that and I'll report back later. Thanks...

What is the rule when loading cartridges for a specific gun when choosing bullets for a given barrel size? More specifically, if you have a 9mm barrel (.355 ID) and a bullet with a .358 OD, will the 0.003 tolerance difference craete major problems or is this a non-issue?
