Collim1 Posted December 29, 2018 Share Posted December 29, 2018 I have a bunch of revolvers. All of them except for one are incredibly reliable. I have a beautiful 2” model 10-7 round butt. It truly is gorgeous. When shooting it get gunked up under the extractor star far faster than any other revolver I own. Sometimes it’s only 18-24 rounds before so much unburnt powder residue is under the star it locks up. Is this a gas ring issue? My model 66 is my workhorse, and often goes several hundred rounds without cleaning shooting the same ammo, and this has never been a problem with it any suggestions?

GuitarmanNick Posted December 31, 2018 Share Posted December 31, 2018 I have the same gun and it has never exhibited anything like that. It is my favorite handgun. The trigger is smooth as butter and it is surprisingly accurate. I can fire hundreds of rounds at an outing without any sign of malfunction or binding. If you have a lot of rounds through it, the gas ring may be bad. If you have ruled out ammo and over lubrication as contributors, there is not much else it could be.

AK_Stick Posted December 31, 2018 Share Posted December 31, 2018 There was a period where S&W didn’t put gas rings in the yoke of some revolvers. Though I’m no S&W expert, it certainly sounds like your issue. Drove a lot of PPC guys off the K frame. Link to comment Share on other sites More sharing options...
Collim1 Posted December 31, 2018 Author Share Posted December 31, 2018 (edited) I’ve closely inspected each of my revolvers. My pre-model 10 has gas ring on the cylinder. No issues with it. My model 64 has gas ring on the yoke. No issues with it either. My model 66 has gas ring on the yoke and no issues either. And my 442 has a hybrid setup, gas ring on the yoke, but the cylinder is cut differently to allow a good seal. No issues with it. The snubby model 10 that’s giving me problems has the gas ring on the yoke, and a bushing inside the front of the cylinder. I don’t understand why it’s an issue. Maybe time to call a gunsmith. I’ve always wanted a 2” six shot to carry and this ine is a beautiful example. I really want it to work out. But I don’t trust it so far.

Collim1 Posted December 31, 2018 Author Share Posted December 31, 2018 I just diassembled he cylinder. I’m really stumped. The cylinder has the gas ring pressed into the front of the cylinder. It’s not on the yoke. I really have no idea what the problem is now. Link to comment Share on other sites More sharing options...

GuitarmanNick Posted January 1, 2019 Share Posted January 1, 2019 (edited) You may want to contact Smith & Wesson. Mine appears to be the same gas ring setup and I do not have any issues with it. I have fired lots of different rounds through it over the years, too. Most of the rounds were not top shelf ammo! Here is a good exploded view drawing of the gun: https://www.gunpartscorp.com/gun-manufacturer/smith-wesson/revolvers-sw/10-7 Are you the original owner of the gun? Is your extractor rod collar(part #4) in place when assembled? If that is missing, it may cause the problem you are having. If you are not the original owner, check for missing parts or something assembled incorrectly. Edited January 1, 2019 by GuitarmanNick 1 Link to comment Share on other sites More sharing options...
Collim1 Posted January 1, 2019 Author Share Posted January 1, 2019 I am not the original owner. I bought the gun used but in like new, possibly unfired, condition. It’s a ~1977. Everything appears to check out. Cylinder is assembled correctly and the fit, lockup, timing, and cylinder gap are all spot on. Its puzzling. I’ve only shot it twice since I had it, so I haven’t really had a chance to start eliminating variables and narrow it down. 1 Link to comment Share on other sites More sharing options...
Moshe Posted January 1, 2019 Share Posted January 1, 2019 I am never the original owners of the 686 or the 66 line. I remember drooling over them when I was younger, and I ended up with Taurus Stainless 66 (Essentially a copy of the 686). But, when you grow up, get a wife, and irritate her, you can end up with 4 pre-lock 686's. Even when you give her the best shooting one with a nicely polished trigger that is smooth in double or single. Link to comment Share on other sites More sharing options...

My 66 is my range gun and carry around the hunting property and my 3” 64 has been a carry gun. Sometimes practicality wins. Link to comment Share on other sites More sharing options...
Moshe Posted January 1, 2019 Share Posted January 1, 2019 I like them due durability. I find the bluing wears off of firearms over time, Link to comment Share on other sites More sharing options...
Dric902 Posted January 6, 2019 Share Posted January 6, 2019 Is it loose, maybe a shim would help the seal. just guessing . Link to comment Share on other sites More sharing options...
Collim1 Posted May 12, 2019 Author Share Posted May 12, 2019 It’s been a while, but I finally made it to the range. I left my reloads at home and shot 100 rounds of Speer Lawman FMJ and 100 rounds of PMC FMJ through the model 10 snubby. No problems at all. No gunk under the extractor star, no sticky cylinder. I guess my reloads with Win 231 are just dirty. Maybe this gun is tighter than all my others and won’t tolerate it. I read Win 231 doesn’t burn completely at light loads. Next batch I load will be the max standard pressure .38 loads. Hopefully it will burn cleaner at that load. I will probably find a new powder when I run out of this. 231 sticks to everything making it a pain to measure and pour anyway. Link to comment Share on other sites More sharing options...
Armorydoc Posted August 20, 2019 Share Posted August 20, 2019 Do you have any cylinder end shake ? Might need shimmed.Sent from my SCH-I545 using Tapatalk Link to comment Share on other sites More sharing options...
GuitarmanNick Posted October 18, 2019 Share Posted October 18, 2019 I have had good luck using Unique pistol powder in my hand loads. It burns fairly clean. Link to comment Share on other sites More sharing options...

Get some Bullseye and only use 231 for your other guns. You might also try titegroup. If the problem persists, find a local gunsmith ho knows S&W's or send it back to the mothership.

ede Posted July 4, 2021 Share Posted July 4, 2021 Load some rounds with E3 (3 to 3.4 ought to be a good spot), it says shotgun but it works well in 38s. I load Short Colts with it and make Minor. I've very clean and never a problem with it fouling up my wheelies. Link to comment Share on other sites More sharing options...
