That says it, my Miroku 92 .357 sucks for accuracy. It has a 'bullseye' rear and a marble fiber optic front allowing a fairly consistent sight picture. I have tried a 358156 with the appropriate amount of 2400 with little luck before switching to a jacketed 158gr and 14.8gr. of 2400. The bullets go in straight, just not close together.
Anyone out there with the miroku having better luck? Give me a hint.
