I have a good size cartridge collection almost 300 rounds now.They all are cases w/ bullets in them the only one that doesn't have a bullet is my 33 WCF.I have rounds from .22 Short to 4 Bore.Hunting rifle and handgun cartridges only.It has taken me 4 years they are in my safe,because if something happen to them it would take forever to replace.I'm always looking for the Big Stuff too Buffalo cart. and NE rounds.I get a lot of rounds from some great guys on here for free and the ones I have to buy I get from Ammo-One.com he a good guy to deal with.Good luck on your collection.If I get some doubles I will trade with you if you happen to have something I don't have.Dave
