I am going to reload for a Browning BAR 7mm RM (first foray into loading for a semi-auto). It would seem that R-19 would be good for a number of my clalibers including the RM, so I was thinking of using it and clean up the powder shelf. I currently use H4350 for 6.5x55, '06, and 375 and quite like it. I did find a recipe for the 7mm RM using H4350 but it seems to be a bit weak￼. The concern with R19 is that I have read it is temperature sensitive which may not be a good thing when moose hunting. The question is: should I clean up the powder shelf by just using H4350 or does R-19 provide a better alternative? I did notice that they sit very close on the powder burn rate chart. Thanks for the input.
