Basic S&W tighten-up?

I've completed some fairly complex home gun plumber projects. I have Kuhnhausen's books. What I'm looking for is more of the 'Idiot's Guide to Basic adjustments". My old M&P and 1905 work ok but I'm wondering if there's a simple way to just tighten 'em up a little. I see the shims offered but don't know much about how to go about it. They work in the old guns? Or should I just relax about it? They are reliable enough for business as is.

I'm looking forward to that article. In the meantime I'll try some heavier bullets. Just got a new mold.

My mistake. I was experimenting on how to brighten up the photos for TT and I got kind of crazy with the editing software. Unfortunately, I was unable to edit the edit and change the text. The original photo is back.

Note re. post #24 above photos of two targets. Both were shot at 25 yds., about 15 min. apart. I'll see how that 10 yd. caption got on there. New to me.

Great! Handguns articles are always well received.

John Alexander has asked me to write an article about this thread topic for the Jan/Feb issue of The Fouling Shot, which I will do.

Just make sure the bullet diameter is the same as the cylinder throats. If the cylinder is not spinning freely when opened, there is a really good chance it is just dirty. Remove the cylinder from the yoke, it just slips off. You don't need to unscrew the ejector rod unless there is an issue with it. Clean the yoke barrel and inside the cylinder where it goes. Little lube on the end of the yoke and put it back together. It should spin freely now.

Not to be a name dropper, but Glen used to work where I still work, and I have met him. He's a hell of an engineer well beyond just guns.

Wonder why the 148 grain wadcutter won't shoot? Were they keyholing? I recall 2.7 grains of Bullseye being sort of a classic wadcutter load. One thing I always do with a bullet new to a particular revolver is to drop a bullet into each cylinder throat from behind. If the bullet falls on through, no need to try it, it won't shoot. Found this out with my Officer's Model Heavy Barrel Match in .32 S&W. Tried some 77 grain bullets for the .32 ACP, they wouldn't shoot, turns out they were undersize, but it shoots very well with the 93 grain intended for the 30 Luger, it's fat enough to fill out the throats.

It's amazing sometimes how loose a revolver can be and it still shoots well.

Thanks for the compliments! I am definitely happy with the way both these old girls shoot. That Lee 125 has shot well in all my .38s and .357s. But, I am going to try some 158s. I have a boat load of molds, including some old Ideal classics. Reading Glen Fryxell's articles makes a guy want to use the oldies, like 358477 and 358429. My intended target load with a 148 WC didn't do well at all in either gun. I may have reduced it too far, around 650 fps. After this new test I agree with Dave, if it aint broke don't fix it. That said, the Victory cylinder absolutely will not spin freely when the thing is opened up. Something wrong in there so fixing that will be the new goal. Loose or not, these guns still shoot as is.

The longer barreled gun may “like” a bit heavier bullet, that should bring it's point of impact up a bit. I think 125 grain bullets were seldom used in .38 Special when these guns were new, no doubt a 158 grain of some sort, why not a Keith type, would do well.

That is damn good shooting, speaks well of both the two revolvers and the shooter.

That's at 25 yards with those fixed sight beauties! Leave'em alone, back away now, don't come within 10 feet with a screwdriver. That's pretty good, 90% of the thousands of officers I trained over the years couldn't shoot that well, even the “gun guys". Seriously though, I was being serious. Let me know how the pistolsmithing is coming when you get a chance.

Tim asked to post these for him. I used Photobucket years ago but the amount of adds makes it a frustrating experience.

I'm sure Tim will chime in and let you know his thoughts:   Dave

I think we have struck gold here boys. I believe Dave is the new official CBA S&W revolver guy. I feel lucky to have his help. I must admit I am tempted by some shortcuts but now don't want to let Dave down! He is determined to 'do it right' so as to avoid problems down the road. Like having a shim come apart and locking the gun up, for instance. My 'Victory' model looks like hell but shoots pretty good. I went to the range yesterday for a quickie. Shot a 10 shot group with each gun at 25 yds. from sandbags. The 'Victory' held about 3 1/2” and the 6” 1905 stayed in 4” with most closer than that. The load was randomly selected from my stash as one that has shot well in about everything I have. My buddy, Wineman, has agreed to post a couple pictures here for me on the condition I learn how to do it myself in the future. I admit I am a stoneage man, really good with an axe or club.

Exactly

Only so much can be learned from books.

Jerry's was a superb gunsmith & his books are good, actually the best on the market, covering a lot of techniques, but I can teach you things not in his books, only learned at the S&W, Colt & Ruger factories. Some of my techniques & tricks were also learned from the firing of over 25,000 rounds a year during my 33 year career and literally working on more than 50,000 (a conservative estimate) revolvers & semi-autos used in law enforcement during that span. http://www.castbulletassoc.org/images/emoticons/fire.gif

OK. Why not? I'll shoot some paper as is for starters. Dave has told me not to expect a big change in accuracy based on our conversation and what I told him about my old Smiths. I've had them for a long time. The idea was to learn how to work on them. This project is about 25 years overdue! Procrastinate much? Now to select a test load.

Not really necessary or likely to be helpful. My understanding of how these babys work has jumped way ahead in a short time. Thanks again for your help and time. I'm thinking I'll need a new hand, cylinder stop, and a little work on the yoke barrel. At least the lockup seems a-ok. On the side, I'm hearing S&W will still take these old war horses in for a factory service. Nice to know just in case.  EDIT; And probably a new cylinder pin. Got a tiny bit of that side to side cylinder wobble on the back end. Next year I think I'll shoot one of these old girls in the CBA's postal match. Well, unless the gun is spitting/shaving lead, it might be at least interesting to shoot a few groups as-is, then a few after tightening up. 

Could make a decent FS article. 

You might want to check the cylinder throats for uniformity, and get them honed to match the biggest one, while you have things apart.  Maybe just using a bullet that fits/shoots well now, just to check that it has the same fit in all 6 holes.

Let me say thanks as well to you, Dave, I certainly learned something reading your posts!
