Annoyed by a Uberti
« on: April 01, 2021, 03:50:35 PM »
Picked up a Uberti 1873 5 1/2" .44-40 a while back because it was just GORGEOUS, the CCH was just beautiful. Today was the first day I took it to the range and it is misbehaving badly. Will not turn to full lock when loaded, needing a twist on the cylinder to fully set. I suspect the hand/pawl is the culprit. Gonna tear it down this weekend and check for burrs, etc. Anybody got any suggestions for any thing else to look for?

Be careful not to lose the tiny screw and/or spring that puts pressure on the hand.  Ask me how I know.

Any chance of high primer? You said “when loaded” it needs help to turn.

Hadn't considered high primers as the stuff I was shooting was from Choice Ammo and ran perfectly in my Vaquero. I will go look at the remaining stuff.

First thing to do before you go all nuts is to remove the cylinder and drop a round into each chamber.  If they are not freely dropping into the cylinder all the way to the rim your ammo is the problem.  .44-40 varies all over the map as far as chamber size.  Your bullets could be to large for the throat.  Also it is very common for the dies not to be setting the shoulder back far enough when the rounds are resized.  Out of four sets of .44-40 dies I have had to have the sizing die shorted by about .060" so they could be screwed far enough down to set the shoulder back.

If the problem surfaced after the first round was fired, then it could be that the spent primers are cratering around the firing pin and then dragging on the recoil shield.  Then you have too large a hole in the frame/firing pin-bushing.  My easy-fix was to switch from soft Federal to harder Winchester large pistol primers.

Okay, this morning went and grabbed some more ammo. The Choice stuff dropped right in and would spin the cylinder and rotate by cocking. This is from the same batch of what was hanging up yesterday. No sign of high primers on the remaining 200 rounds. Fiocchi and Winchester also cycled fine. I even tried some HSM .38-40 to see if the cylinder would go around and it did. Now none of this was live fire [especially with the 38, just curious as it has the same lower half dimensions] so I will have to open the gun up I guess. There was no obvious cratering of the primers in the fired stuff.

So ammo spins in the cylinder fine, but then only hangs after shooting?  That sure sounds like backing out primers, but shouldn't happen with factory ammo (or in this case, Choice Ammo is maybe "factory reloads"?).  Look at the fired brass for any scrape marks on the back of the fired primers or the brass base.

Years ago, I had a Colt that behaved in a similar manner.  Solution was to wipe the chambers and ammo with acetone on a rag.  Once the brass was fireformed to the chambers, the problem ceased.  Might be worth a shot. . . .

Thanks, will try it out.
