Wow! A lot of great information. Thanks all. I have 158 gr SWC bullets on hand but no 2400. I've been using 231 for my 38 special loads. I'll have to pick up some 2400 at the next GS. Years ago I used 2400 almost exclusively in antique black powder single shot rifles loading such cartridges as 44-77 Sharpes BN and 43 Danish. Haven't had any in years, though. I think this will be fun. I have newly acquired post war 38-44 Heavy Duty in 4" and Outdoorsman in 6.5"
