S121

Hi guys does anyone have any knowledge and of course loads for S121 in 12g use. As a very cheap form of propellant, I was wondering why it seems less popular. I use #3 and #7 mainly. I will obviously be testing before trying someone's load, but it will be nice to test a load and know it workd for someone else.

I'm loading 20.5gr of s121 for 28g #7's. Have no idea what the speed is over a chrony, but its a good load for pigeons and the odd duck at close range.

At the moment I'm having better success with my reloads than with factory ammo.

close to what I have worked out as a mid load ---- thanks boet
