I do load the caliber, but only in my replica 1873 winchester, and only with real black powder.
I think you're going to have a hard time finding someone who has a 44-40 barrel made up for an Encore frame to talk to about it. Even on the Contender frame, I'll bet they're not many takers. I have a 45 Colt carbine barrel for my Contender, but I've not hunted with it.
You may do well to just get a 44 mag barrel and keep the load down around starting load. Plenty mild recoil in that huge Encore frame. I seriously doubt it will knock you around any.
And for the record, the 44-40 case isn't any harder to reload than any other case. You just can't be unconscious when you load. I've NEVER crushed a case either sizing, seating, or crimping. All it takes is a normal level of care in the loading process. Pretty easy really.
