I found a load for a 55gr jacketed bullet in the latest edition of the Lee reloading manual. Starting load is 39.0grs never exceed 41.5grs. I tried those loads I cooked up today and shot a genuine MOA group, I shot two acutally but one group was a bit larger because I flinched. I am now loaded up to 41.5 but its too dark to shoot now so I'l try them tomorow.
