The Henry is dead on with iron sights
 

last time I shot my new gun it was hitting low left and I was looking at my front sight and noticed it was a little off center right... I was not going to worrie about iron sight because I plan on mounting a leupold VXII 1-4x20mm on it... Well ol lady slipped out to do some shopping and I figured I'd shoot the remaining 10 rounds I had left.... I used a brass punch and drifted front sight to left to center over bore by eye and I looked at rear sight and it looked a little off center to so I drifted it over center of bore also... I raised rear sight up two notches on ramp and went out and fired it at 25 yards and put 5 rounds in in a tight cluster dead center tad bit low... Moved target out to 50 yards and fired 5 rounds and shot a 1" group... I was very pleased with how it shot and I can't wait to get that scope mounted and sight in dead on at 50 yards

Sounds like you got a Winnie.
