First of all, shooting a Henry for speed is an oxymoron. If you shoot a Henry, you just ain't gonna be competing with the boys with the short stroked '73 short rifles shooting light 38 Smokeless loads. Not in this Cowboy's humble opinion anyhow. With a Henry, it's all about style, particularly if you shoot BP. Just my opinion of course.
Here are some photos of my 'spacer stick'. I prefer to call it that rather than 'cheater stick'.
I made it by putting 10 rounds in the magazine, then made the stick slightly shorter than the space left over. I consider this to be a bit of a safety improvement too, since there is only about 1/2" or so of free space for the follower to travel if it should happen to slip out of my fingers while the gun has 10 rounds and the spacer stick in place. The follower won't get up to full speed only travelling about 1/2". The piece of brass tubing I put in the stick rides in the same groove the follower tab rides in, the brass tubing stops the stick from feeding all the way into the cartridge elevator.
I hold the rifle just in front of the reciever, and allow the stick to slide above my fingers as the last rounds feed into the action.
One of my pards has been shooting a Henry for a long time in CAS, and his method is to shoot 5 rounds, then do the 'Hop', then shoot the other 5 rounds. But he mentioned to me just the other day that he is thinking of making a stick like mine.
