I stumbled into a large amount of AA 4100 powder for an extermely good price (Less thank $7 per pound with shipping/hazmat). I know this powder is very well suited for 357 mag and 44 mag, but has anyone ever used it in rounds like the 22 hornet, 256 win mag, 221 fireball, 223, 357 max, 357 herrett, 357/44 Bain and davis....Anyone got any ideas?
thanks and regards,
