I just un-boxed my pre-inherited RCBS Rock Chucker Pro Master Kit last night and I'm all excited to get started. I want some suggestions on some good powders to get started with.
The calibers I'll be loading for initially will be .45 ACP, .45 Colt and 7.5 x 55 Swiss. Soon that will expand to include 12 Ga (As soon as I buy a MEC Sizemaster) 5.56 NATO, 8mm Mauser, 308, 357 and 9mm....My neighbor gave me a 3lb can of Winchester 296 and some primers. I have some doubts about how useful the Winchester 296 will be as it seems better suited for .44 Magnum and other hand cannons.
I will primarily be loading for Cowboy Action Shooting, range trips, busting clays, and the occasional USPSA or IDPA match. Obviously the .45 Colt will be for Cowboy, and probably .45 ACP for Wild Bunch. The 7.5 x 55 Swiss will be for Wild Bunch as well as range blasting. I'm having very limited success finding any suitable loads listed for the 7.5 Swiss for Cowboy though it's been suggested that I can probably use something along the lines of 308, 30-06 or 303 British as a starting point. These will be very low performing loads probably around 1300 FPS so I have little concern about blowing up my gun, probably wouldn't even happen if I double charged it as the levels I'll be running. Obviously all the Cowboy loads will be lead bullets only.
Powders I've considered include:
Trail Boss
Winchester 231
Tight Group
Universal Clays
Powder Valley seems to have decent prices and a good variety to pick from. I have my C&R so get good deals from Graf's too. Gun Broker seems to offer some good deals on bullets. Any vendor suggestions?
Thanks!
