Have a fellow SASS shooter that his Uberti started doing that. Never could get it to stop and finally had to change the barrel. That fixed it. The gunsmith that did the barrel swap said that his original chamber was oval instead of round. He tried to get it repaired under warranty but they would not do it because it was short stroked so if you try make sure you return it to original before you send it in.
The first thing we determined was it was not the ammo because the ammo would shoot in all other rifles and none was sticking. Then we cleaned the hell out of the chamber using scrappers for carbon and everything we could think of but 1 or 2 out of 20 would stick after they were shot even after the cleaning.
This rifle was just under warranty so it was sent back to Cimmeron but they refused to cover it under warranty because it had a short-stroke kit in it but they had originally agreed to change the barrel.
He had them return the rifle and sent it to a local gunsmith that changed the barrel and his diagnosis was the chamber was not round. That is the story. Hope this info helps!
