I think you'll be sufficiently outfitted there. I would suggest you pick up some 00buck and slugs for the shorties. I also suggest you find some 147gr 9mm to run through the cans. Don't forget .22lr too!
I need to look harder for some 147 gr. I might have to try and get down to Bradis and pick some up. +1 for the 00buck and slugs. I'm not sure I want to shoot those out of your miniature canon again! I went back and added the bulk pack of .22, I spaced it.
