I bought a used MEC from a trapshooter that was set for 1oz #8, 18 grains Clays, WAA12SL wad, Win 209 primer, AA or STS hulls. I shoot trap, skeet, skrap, 5 stand and SC with this setup with good results. I use the same setup for 7-1/2, 8, 8-1/2 and 9 and have no complaints. If it's not broke don't fix it.
