I actually shot skeet the other day.
Fella I shot with had 410 tubes in his blaser was using challengers 100$ a flat he mentioned, let's them hit the ground. Got 410 style brakes and a couple 24s looked pretty good to me.
I have thousands of AA 410 hulls from a privet school that had a skeet lay out. They don't seem to get much more than 4 or so loadings have new hulls improved any?
