Used to use its cousin [452AA] in .30-30 with cast bullets; still use it in .32 S&W and .32 S&L Long loads for my Favorites. Never could get it to shoot very accurately in any of my .38 Special / .357 Magnum loads in my Ruger #1's, but think I may try it in my .32-40.
Last time I bought some, there was ~8#'s left in a 10# keg which cost me a 12-pack of wobbly-pops that we proceeded to finish before the seller went home.
That was a few years after I cut open 2 flats of my old trap loads, which I initially cut-up just to salvage the shot, but figured why waste good powder.
