Hi all, I'm new to reloading, starting to gather all the needed supplies, and I'm looking for some expert advice on powder. I plan on loading 38spl, 357mag, and 45acp. Plan on using lead bullets. I'm hoping to start out fairly simple, so I'm looking for recommendations on a good powder to use for both calibers. If its makes a difference, they will be fired from a 4" Ruger security six and a Colt 1911 Gold Cup Match. I'm looking for good/fairly accurate plinking rounds, doesn't need to be super hot. Thanks in advance guys, really appreciate the advise.
