Go with what ANTS said;
HP38/Win231 is superb in the .38, 9mm, .40S&W, and .45acp. Good enough that when Precision Delta ammo was setting a bunch of National records in PPC competition, it's what they were using in their factory ammo. Others are good (Unique, Universal) but, for ONE powder, give me HP38/Win231.
For the two rifles, Win748/BLC2 (again, the same powder- just different labels/lot#'s) is one of my favorites. Yeah, I really like Reloader15, but, push comes to shove, I'll stick with BLC2. My Rem M-7 in 7mm08 has a definite preference for BLC2 for velocity AND accuracy. (Sorry, but I've never gotten the velocities listed for Varget, neither has it exceeded BLC2 or IMR4064 for accuracy, in my dozen or two rifles.)
Use Federal (NON MAGNUM) primers in the appropriate size (You'll need 4- lg and small pistol, large and small rifle).
