I'm going to start shooting IPSC shotgun and need to know what's the current hottest gear in the 3gun circuit. My initial plan is a Benelli M2, 26" barrel and a pretty long mag tube....thinking +9 or something. I have the actual shotgun part pretty much dialed, but as far as ammo carrying options I'm completely clueless. So, what are the top 3gun guys using?....talking quad load obviously.
