I run 200 gr leadbullets through all my 44's, With 5 grains of clays I'm getting 920 fps from a 7.5" ruger bisley, it's mild, acurate and clean buning. Your choice of 2400 is kind of poor powder for this type load you are looking at, between unburned powder and fouling you will have to deal with cleanning your handgun alot. 2400 was ment for fast semi hot loads and a good roll crimp to burn all the powder. When I load 44 special it's unique or bulleye . My 2 cents if you want the advice.
