I have been loading for a .38spl and .357mag revolver for a while....but mostly using mouse fart loads for my model 12 airweight and low end 357 data for my 686. I find myself wanting to load some full power 357 loads...what bullet should i look at? i have been using 158gr plated berrys w/o a cannelure so far for plinking. for full power loads i ASSUME I need a bullet w/a cannelure for a proper roll crimp? thanks guys.
