Do not reduce H110 !!

Which 3" .44 mag is it?
I have a 3" .44 mag ported trail boss performance center 629.
It's a large, heavy, stout wheelie that could be used as a hammer if need be.
I use it for a 'walking in the woods' type gun for killing pests like raccoons, etc.
I use 24.0 grains of H110, with 240 grain XTP hollow points and they are max loads, and because it's ported, the recoil is actually less than a starting load.
If you have a revolver that's old, or light in weight, or it's not ported, or you don't happen to like loudenboomer noises then I wouldn't recommend it.
Try a different powder if you want less power, just don't reduce H110, everybody I know advises against it.
