4.6 grs of Bullseye with a swaged 200gr bullet is on the warm side . For Bulleye I use the Zero swaged 200SWC with either 3.6grs VVN-310 or 3.8grs Bullseye . If you need the speed a cast or jacketed will hold up a whole lot better . 4.5grs of Bullseye with a Nosler 185 JHP or Zero 185 JHP are very accurate target loads that avg 780fps from a 5" Govt 1911 .
