I've got an Izzy 91/ 10 that I picked up a while back and needed some work then and I gave up on, until recently. Now, I'm back at it. When fired, the case get's so lodged in the chamber, the bolt has to be beaten to rotate, then come back, while leaving the spent case still chamered which then has to be reamed out by a long rod. Headspace problem? I saddly, I have no gauges either. Oh yeah, don't worry, I've only fired it twice and don't plan to do so again until I get the issue resolved! Lol
You did not mention the ammo type, but laquered steel cases are notorious for getting stuck in the chamber. A thourough cleaning and/or polishing of the chamber is in order.
Mosins seldom have headspace problems.

Looks like Ken nailed it. But what is a 91/10? Do you mean 91/30? "Sticky bolt" is a pretty common problem, and a good cleaning is in order of the chamber, and where the bolt head locks in the receiver. A good cleaning of the bolt to ensure there is no nasty dried up cosmolene on it or in it is a good idea too.

First, it is a model 91/10, not 91/30. it's a little more unheard of then alot of others. It was made in 1910, the first year of production for that model. Second, as for cleaning, I've cleaned the chamber with a drill and a 20ga. brush already. I burnt up three brass brushes doing it even. I clean all of my guns very thoroughly and I've cleaned the bolt multiple times. It's spotless and operates smooth in either one of my other Nagants. I've sent some empty shells through it just the other night. They didn't seat fully, nor get deep enough into the chamber for the bolt to be rolled closed. Then I had to beat the handle back to eject the shells. I noticed on every one of them I sent through it that the where some gouges on the shells just a bit up from the bottom (rim), as if there where some sort of burrs in the chamber walls. I looked through the chamber with a light and couldn't see any burrs, or any real impefections. The chamber looks smooth and clean.. Any idea where to go from here?
So is a 91/10 another name to call a Dragoon rifle then? It is interesting you call it a 91/10 as it is not listed in the book I have done research in. This is the first I have heard anything of a 91/10. Do you have some pics of this rifle? And if you are getting scratches or gouges on your case, then it is some kind of burr that is doing it. You're going to have to get something in there to file, or sand it down so it won't impede travel of the case in to the chamber. Pics of the cases in question could be helpful too.

they have alot of models of the M91....they would do a lil change here and there and make it better then assign it another sub-model(which is what i'm calling the 10, or 30 on a 91-30). if i remember correctly, there were alot of those around the beginning teens.
The 91/10 is about like the M91, just it has the upper hand gaurd, different barrel bands, and was made to use the spitzer rounds with higher chamber pressures, instead of the original blunt nose ball rounds. I too, figure there has to be a burr some where, but I haven't been able to find it. I'll post pictures of the gun and shells soon.
Ok, attached are some pictures of my 91/10 with my 91/30 showing some of the differences. My 91/10 is an infantry model. (Dragoons where a little shorter) The top rifle is the 91/10. The bottom rifle, the 91/30. The first one shows how the overall length of the 91/10 is greater then that of the 91/30, but about 2''. The second shows the difference in the upper hand guard, the front sight (it's just an unprotected blade where as the 91/30 is the hood and post), and forward barrel band. The last, shows the difference in once again, the hand guard, but then also the rear barrel band and the rear sight. The sight on the 91/30 is measured in meters and is the common slide type, where as the 91/10's is measured in Arshins and is a rather odd, latter type. The last picture is showing two empty shells that I feed through the 91/10. This is to show you guys how it's gouging them. Keep in mind, the shell doesn't seat fully, but darn close. Sorry about the poor quality pictures.
Looks like a serious burr in the chamber. Take a 20 gauge or 12 gauge bore brush, put it in your drill with a patch wrapped around it and use 600 grit lapping compound and polish it, but don't do it too much. Too smooth a chamber will cause excessive brass flow and serious pressure problems.
Thanks for the pics. The cases look quite disturbing. I would rather see one in person before making further comment on what the issue is and what to do about it. I would probably run it by a gunsmith.
A similar problem occured with a 91/30 of mine. There was damage on the chamber wall that could not be repaired without setting back the barrel and rechambering. I was able to buy a barrelled receiver to fix that problem. That mongrel is one of my favorite shooters.
While not too many folks recognize the milestones in the old M91 rifle, this is the first time I have heard a reference to a 91/10 to denote the last major variation of the old M91 Infantry model. There were many changes made during the 1908 to 1910 time period. Brother Ted illistrates them very well here. Russian/Soviet M91
I have a 1906 that had the rear sight and recoil lug updates but retains the other earlier features. Thankfully, it's a great shooter.
Keep us informed on the chamber problem. I fear you may have a wall hangar though...

what were those two rounds shot from? if they were fired from another mosin, don't expect them to fit any other mosin unless you resize them first. one of the first things i learned about mosins is to never chamber a fired round from another mosin. you can try, but DO NOT force it. they can get stuck bad.
if i had a mosin version that rare, i'd take it to a smith to verify the headspace and check the condition of the chamber.
not something i do normally, but i think this one's worth the trouble.
