The cimmeron (Uberti)Henry is a great gun. And you got it at a really good price.
But remember, with a brass frame, you can't load it too heavy.
The only issue I have heard for the Henry's (in any caliber) is when you load the tube, ease that spring loaded plunger back down onto the cartridges. If you only load 5 or ten, then "let her go", the spring can send the plunger down hard enough to detonate a round. Now this is not an every day occurrence, but it happens frequently enough to use appropriate caution.
Now for the good stuff. They shoot like a dream. And the 44-40
LOVES black powder. The necked case nearly eliminates blow back keeping the action surprisingly clean.
I have an 1866 Uberti. For CAS I use 25 grains of 3f, a little cornmeal (just enough to compress the load slightly, and a 205 gr spg bullet from Powder Inc.

It shoots to Point of aim at 50 yards. Sounds like a howitzer, but with only 25 grains, the recoil is like a 22.
And... shooting black powder slows you down. Before you crank out another round, you have to wait for the smoke to clear.
Great fun... Enjoy your new toy, my friend.
The problem using historical quotes in your signature is that there is no way to verify its authenticity.
