There are two versions of the Henry. The old is black inside the stock the new one is orange. I have one of the new ones and have just over 4500 rounds through it with about a 5% failure rate. That's all FTE, FTF and misfires combined. That number is a little higher than it should be because it includes trying to fire all the .22 ammo I find on the ground at the range and some slightly damaged cartridges. They need to be broken in a bit at first.
The Henry is buoyant but will sink after a period of time. I find it is most reliable with copper plated ammunition that is 1200 fps or faster. I have used ammo up to 1800 fps but mostly I use CCI Mini Mags both the 36 gr and 40 gr.
I get about 1 to 1.5 inch groups at 25m with the peep sight but my eyes are starting to wear out. I can hit an 8" pie plate with a 3" black dot offhand out to 70m with 40% of the rounds in the black dot at 70m. There is a POI shift when I get the barrel hot by dumping rounds through it like 8 mags as fast as I can. The front sight is driftable for windage and the rear sight is adjustable for elevation. Putting optics on it improves the accuracy but then it can't be stowed. It has a 3/8" dovetail and Henry makes a Picatinney rail that slides on and is secured with set screws. The trigger pull is stiff but does smooth out a bit over time.
Spare magazines are a bit expensive but you can order directly from Henry and they ship to Canada now.
Overall I am happy with mine and I actually shoot it more than my other .22s.
