as far as components go, you opened up a can-o-worms there, bro...

I use AA hulls for my skeet & trap loads, and actually those black lowbrass Remington "Game Load" hulls for my field loads...

now, when you look in a reloading manual, you have to match the wad to the hull... most manuals will say something like "AA hull, WW wad # blah blah "white", 1oz lead shot, 7.3 gr IMR 700x MEC bushing #23 or someting like that...

so make sure you match your stuff up for good results...

I thought of buying an adjustable charge bar for my MEC, but bushings are cheap in comparison
