.44 Remmy tune up??

Here's a question for you revolver tinkerers. I have been shooting a bunch a balls through my Remmy C&B revolver lately and have noticed that the bolt is wearing a groove in the cylinder before it pops into the notches. Not just one but all six all around the cylinder and they are all wearing evenly but it is an eyesore to have grooves cutting into the cylinder walls. My Colt doesn't have this problem. The Colt's bolt pops right into the notches without any drag on the outside of the cylinder.

How do you go about fixing this problem?

Thanks,

remove the stop and polish on buffing wheel. better to have the stop a little tight than loose.

This is a pretty common issue. Colts do it too. So do many modern revolvers.

There are a couple of simple tricks to tune that out. First off, remove the bolt and carefully buff out any burrs. Polish it a bit so that the contact area is shiny and even. This will reduce wear where it touches the cylinder.

Secondly, while you have the bolt out, back off the screw that holds the bolt/trigger spring in place. It doesn't take much backing off. Usually no more than 1/8th of a turn or even less. I locktite the screw so it will hold the setting, but I'm not sure that's really needed. This will reduce the pressure that it puts on the cylinder, or eliminate it for the most part.

If you adjust it right, it doesn't effect timing. If you unscrew it too far, you'll notice it skipping the notch occasionally. If that happens, tighten it every so slightly till you find the sweet spot where it doesn't rub, but it stops the cylinder reliably.

The real cure is a replacement that is oversize enough to fit properly. You may have problem finding one. If I remember correctly, they are similar to a Colt in the way they work. There should be a rear arm that rides over a cam on the hammer. That is where you do the major fitting in that the arm has to be ground so that it is timed to allow the bolt to pop up at a given point on the cylinder. A tad bit involved if you have never done it before, and still a bit involved if one doesn't do it on a regular basis. You need to have a full understanding of what needs to be done, and how to do it.
