recap: trying to find a heavier bullet for metal silhouettes that's as accurate as the Rem factory .38 +P 125gr SJC HP's.
Even factoring in my limited shooting skills and a low-budget rest, it doesn't appear to me that either of these two powders will work well with 158gr SWC's. :(
Back to the drawing board, I guess.
I'm open to any and all feedback.
