Rancho Roy Posted August 31, 2023 Share Posted August 31, 2023 Yesterday I had to repair another 38/357 bolt "lip"....A common problem is that this "lip" gets bent down caused by crud being in the slot under the barrel chamber. This little protrusion lip is very fragile. Once it bends down it will snag on the hole it runs through in the receiver. The 45LC large rim rifles have this "lip" heavily reinforced mitigating this issue. Can anyone offer why this isn't done with the small rim cases? I understand in newer Uberti 1873 rifles this piece is not replaceable. This shows its vulnerability. Has anyone made this modification by cutting a slot in the receiver and reinforcing the lip on the 38/357 like the large rim cases have? Link to comment Share on other sites More sharing options...
Kid Rich Posted August 31, 2023 Share Posted August 31, 2023 A little more powder means a little less fouling means a little less breakage. kR Link to comment Share on other sites More sharing options...

Garrison Joe, SASS #60708 Posted August 31, 2023 Share Posted August 31, 2023 I've never found the pocket filling with dirt to damage the "CARTRIDGE SUPPORT TAB." Even on .38 special fed rifles. What I HAVE had to repair several of was the bending and snapping of the tab in an out-of-time rifle, after a poorly done short-stroke kit install. The newest Uberti approach is to install a replaceable tab which is as easy to replace as the extractor. I'd modify the bolt to accept a replaceable tab LONG before I modified the frame. Several cowboy gunsmiths do this now. Old gunsmith adage - Work on the cheapest part instead of the most expensive part. good luck, GJ Link to comment Share on other sites More sharing options...
Rancho Roy Posted August 31, 2023 Author Share Posted August 31, 2023 Correct, an out of time rifle will usually just snap the tab of. Not bend it down about .001".....Not only can a dirty tab pocket cause this, but a dirt, bound up extractor can also cause tab bending. Link to comment Share on other sites More sharing options...

Frederick Jackson Turner Posted August 31, 2023 Share Posted August 31, 2023 The newest Ubertis have at last gotten around to milling that channel in the bottom of the bolt, and installing a replaceable tab. If yours doesn't already have that channel, it might be worth it to either buy a new bolt, or have your 'smith modify the existing part. It'll cost about the same...

SGT. ELI 35882 GUNFIGHTER Posted September 1, 2023 Share Posted September 1, 2023 I repair the bolts so they will accept the uberti replaceable tab. If something happens then the shooter can just buy a replacement tab. I also add a coil spring like I do for the extractor to allow a little give to them.

Sounds good...I'll sent you my old bolt for conversion once I get the new bolt...Good to have a backup... Link to comment Share on other sites More sharing options...

The lever screw loosens sometimes, but on both of our Marlins they seem to have one thread that is tight, so they really don't any looser than about half a turn. Doesn't seem to be an issue. Haven't had to tighten any in years since going the LocTite routine. Link to comment Share on other sites More sharing options...
Rooster Ron Wayne Posted September 2, 2023 Share Posted September 2, 2023 I found the best solution for screws coming loose on a Marlin. This also works to cure that dreaded Marlin Jam. Leave it in the gun safe and use the 73 ! Link to comment Share on other sites More sharing options...
