Looking for info on loading cast in .375 Ruger cal. have a 265gr gc mould. this is a rather large case. anyone have anything to share here. not a lot of info in the new reloading manuels. from what i see 375 H&H is really close and might double over to some extent. have tried imr-4350, imr 4198, h380, h335os (use 3031 data) even tried red dot. none of the above has given me anything to brag about. sure would like to hear what others are doing. what say you?
