357 Sig w/ 124 RMR FMJ FP (match winner) over Win AutoComp and Win Magnum Small Pistol Primers 1.14\” COAL
I like 7.8gr and 8.0gr of Win AutoComp. Both loads have low SD\’s. The 7.8gr seems to have a bit better accuracy.
Always use a Lee Factory Crimp with a light to medium squeeze…..not just for safety, but you\’ll get lower SD\’s than without.
In a Glock 24 with a Lone Wolf 8 inch 357 Sig barrel, these fly at a little over 1500fps. I run the 7.8gr in a Sig Sauer SP 2022 and it likes them too!
The 124 Gr. RMR Jacketed Hollow Point is a very similar Boolit. I use the same load on them, though I have not performed extensive tests
