My local shooting range is going to offer a shotgun only match that will require at least 30 rounds to be carried out of the gun. I currently have a carbon arms pin wheel that holds 10 and an invitcus practical caddie that holds 8. I load 2 strong handed and perfer the carbon arms caddie. What should get to hold the additional shells? I was thinking about getting a carbon arms vest but I wasnt sure what other guys perfered for shotgun only matches.
