Ed:
That's not a bad group from your carbine. Is that a Chaparral (I can't see much of it, but the rear sight suggests it)?
As far as smoothing, like I said, my Uberti didn't need as much as I anticipated. I'm not much of a gunsmith, but I smoothed some of the inner parts, like where the lever and lifter springs ride. I also noticed that the bolt was rubbing pretty hard on the opening in the frame where it passes through. I sanded the opening with fine sandpaper on a dowel until it didn't rub so much, which helped a lot. The main thing that I did to reduce the "hitch" in the cycling had to do with the lifter arm. I noticed that the rounded part which rides inside the lifter had a knuckle on it. It seemed that as it raised the lifter, there was a hitch when it got to the knuckle. I filed the end of the arm to a more rounded profile, which helped a lot. I haven't thinned any of the springs, but I did back out the screws for the lever and carrier springs until they didn't require as much force to operate. I keep thinking that I'm going to file those springs down a bit, but so far things are working just fine.
There is more that could be done by someone with more knowledge and ability, but those slight improvements have worked for me.
Thanks, fellas, I figured that you'd appreciate hearing from someone who is pleased with his old fashioned gun.
