Winchester AA or Remington STS shell
Winchester "grey" wad WAA12L
7/8 ounce shot
Winchester 209 primers
Alliant Red Dot powder 16.5 grains.
Perfect for CAS, it effectively turns a 12 gauge into a 20 gauge.
Winchester AA and Remington STS shells are super slick on the outside and drop out of the shotgun chambers without having to be pulled out. This is important for shooting SASS matches where you want to reload fast.
I don't shoot SASS much anymore, but I do shoot a lot of muzzleloading trap and there is a black powder cartridge catagory.
Here's my black powder trap load.
Cheap Estate shells picked up on the range, I'm not going to re-reload them.
80 grains FFg
one "nitro card" over powder
a half inch fiber wad, dipped in mixture of 1/2 beeswax and 1/2 Crisco
1 1/8 ounce shot
The ML trap rules don't allow plastic wads.
