I have shot a fair amount of tula, and although it is my favorite Russian steel round of the 4 major's, it is also the only one I had an issue with. ar15 in .223, the extractor broke the brittle rim off and with the steel tight in the chamber. wasn't a huge deal, but it's never a good feeling to be pounding on a cleaning rod muzzle side. steel doesn't spring back after expansion the same way brass does, and it's not as malleable, so when something is off then it's usually stuck in there pretty good and takes a fair amount of force to release it. I have had many stuck rounds in pistols, using boolit's that were too large, simunition w/o a conversion barrel, poor case flare reduction on my part etc, they have always been able to be removed via muzzle on a wood surface, clearing the barrel, and pounding on the back of the pistol. not fun and can mar up your finish, but it works,
