Some years back, a regular and oft recommended load for .357 was 8 gr. Unique with most any J or cast 158 gr. bullet. It was as common as dirt to see it recommended, and I and friends shot thousands and thousands of them. I quit taking the glossy mags long ago now, and haven't kept up with new developments because of that. So can anyone tell me why I never see Unique in any of the manuals any more, except the really old ones I used way back when? What have I missed?
Got my Security Six slicked up and want to take it out for a spin, and that's one of the loads I want to try in it. I see in Lyman 47th that they recommend 7 gr. of BULLSEYE but nothing with Unique! They also show only 7.5 gr. of Herco with 158's, which is notably slower than Unique in all uses I've seen. If 7 gr. Bullseye is OK, why would 8 gr. Unique NOT be????? This doesn't make sense to me. Can anyone help me here? Has piezo pressure testing revealed it has some sort of dangerous secondary pressure spike, as I've read about with some other loads? What gives? Seriously, I need some help here, and thanks for any explanation/info you can provide.
