I've tried several, so far my favorites for fun shooting and plinking are:
19.0 grains of 2400, 405 grain RNFP, Winchester LR Primer
13.0 grains of Trail Boss, 405 grain RNFP, Winchester LR Primer
I'm still looking for a load I like using a real rifle powder, I've tried H4198 with good results, but consistency has been hit or miss. Perhaps a heavier charge could be better, as it works quite nicely in my .444 Marlin.
