I've just picked up a new S&W 500 8 3/8, love it, I've been reloading for smaller calibers, 9mm, .40, .45.. etc.. never a 500. I've got some Rainer 300gr plated HP for target/less recoil, but i've yet come to find any load data for. I have the following powder on hand, AA#9, LiL-Gun, W296. I've called Rainer and they havent gottan to me, so I've stubbed across this site and wonder if anyone can assist with some load data.
Any guidance will be greatly appreciated.
thanks
