I "almost" agree 100% lol 2400 is dirty , but works great and has been the go-to power for the 44mag from the get-go the Elmer K. load - cast SWC was loaded with 2400 way back when , however w296 and H110 are cleaner and less temp. senative. and there are more loads to pick from useing H110/W296 as they are the same power from the same spout at the factory, so if you find a load for 300gr xtp and it list h110 and you only have w296 you can used that , it is the same and there 3 others , but I can't remember what they are , you can get this info from loaddata.com
the up side too the power you are useing is that you can get twice as many loads out of a pound of power , but BE CAREFUL ! you can over charge very eazy !
I have loaded 44mag with Bulleye, (even hotter than Unique) H110, W296,2400,Universal and Unique, all have there ups and downs , I feel W296/H110 is the best way to go as I also load for two 44mag autoload rifles , and they need the gas to work , Unique wont even kick out the brass ! and make sure your primer matches your load ! some loads call for mag , some for large and some for rifle with a 44mag ,if a primer fits there is a load that uses it , good luck , and you may want to join Loaddata.con there not room here to tell you what I have learned there !
