Taking a class in September and need 300 rounds of 00 buck, slugs and bird shot…slugs and bird I have…the 00 I’m lacking. From looking there are only a couple brands that have the shot in a cup and not just setting on top of a wad base. While this isn’t really a problem, the thought of cleaning the lead out of the barrel is not something I’m looking forward to. So, what’s out there in 00 buck ammo with the shot in a wad cup? I know Federal flight control is in a cup but purchasing a couple case of that is going to be cost prohibitive, just looking for some “cheap” stuff I can use for training and save the good stuff for actual HD use. Thanks for the help.
