Annoyed by a Uberti

<< < (2/4) > >>

Cap'n Redneck:
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.

DeaconKC:
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.

Abilene:
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. . . .
