Excuse me Don, this is not a criticism of your post but I think the quest for a more powerful load in .44 special now days, at least for me, is to get it in a lighter package than a .44 mag.

I have a 629 Mtn Gun in .44 mag which I don't carry while deer hunting any more, I use a mod 66 instead which is considerably lighter, I also use a Marlin 336SC in 30-30 instead of a 9 lb bolt action, scoped, 30-06
Mauser.

That said I'm 65 and sure that you younger guys aren't concerned
with weight.
