i finally have a way to reload our 3" 410 shells. i had picked out some wads that i thought would work. only to find out they are for 2 1/2 inch shells. i have no idea where to find a wad (shot cup) chart for this. the guy i bought the reloading tools from said he has used cardboard cut to the right diameter to fill the extra space with whatever he was using. but that sounds so hokey, it isn't even funny. the last shotshells i loaded was over 20 years ago, and i had the right wads. i would like to do that here. but i need a little help to get the right ones
