I have two loads for my 44. First is a plinking load, it is 6 grains of Unique under a home cast 240 grain SWC. even in my 329PD that is super light they are quite pleasant. My big boy load (what I carry when hunting) is a home cast 270 grain RNFP that I load over 19 grains of 296, it is quite snappy in that light revolver. You could probably handle a few more grains as the 19 is right at the minimum. I always put a good crimp on my loads, even the light ones.
