Oh wow. Starting with the 2 hardest shot shells to load. Just a heads up..you will get the best patterns in the 410 from the 2 1/2 inch shells. Others will say not but I've been loading the 410 for years(45 of them in fact). and the 2 1/2 inchers are so much easier to load and much easier to find cases for too. So at least start with that length. Remington shells are easiest to find...and load.. too. most any wad will do but try the duster wads first and use either lil gun or Hercules 410(410 is best). In the 28 ga no shell is actually best. I load the STS Remingtons as I have about 5000 once fired but I also load the Estate 28 ga too. They don't come out as pretty but they are easy to find and fairly cheap. You do have to use the Federal wad in them though. In the Remington I use the Remington PT 28 but am trying the 28 ga duster now. Loads ok so we'll see. 28 ga powder..unequivocably the best and easiest to find is UNIQUE 12 gr in the Remington 13 in the Estate and Federals. I love to shoot the 28..my favorite dove ga and great for quail if ya can find any. Works good on close pheasants. Used my 870 28 on Field trial pheasants a few times but the people running them thought it was too small...never missed a bird with it though. If you want any more info PM me
