Inky7	Bolt issue..... Help???	Lead	[-]
Posts: 58 (04/03/09 10:17 PM) Reply Quote More My Recent Posts Message Me Connection Blocking Invite Ignore User's Posts Report Post	Tags : None Hello..... I have a 1925 Izzy 91/30 (ex Dragoon) that has an issue with the bolt. Without a round it's easy to close but I have to really horse it to close when I chamber a round. I've visually inspected the chamber and bolt lug races and it's all very clean. I've run about a hundred rounds through it and it has no issues extracting but I have to really force it to get it to open. The serial number on the bolt matches the barrel but was probably renumbered when it was refurbed. I've also tried 5 different types of ammo and its the same with them all. Any thoughts? Thanks in advance....

Could be a burr on the inside of the chamber walls itself.....if that's the case, it'll have to be carefully buffed out just enough to make for smooth closing on the case when loaded.....

I got it out of a fixer upper bin a few years ago. Try this: 1) Remove the bolt form the rifle. 2) Attach a round to the front of the bolt. 3) Reinsert the bolt and see if it now closes properly. That is how mine worked. I tried just about everything the experts on the board suggested with no success. I eventually found a bolt form one of my other MN's that worked fine. It is the only bolt that works properly in this rifle. The bolt from the M91 works just fine in all my other MN's too.

These sort of problems are usually related to the extractor being either dirty or bent or out of position on the bolt head. Curt

Renfield54; the chamber is smooth... spent shells get extracted properly and the cases look fine after firing. It's just difficult to close or open the bolt with a round in the chamber. gaweidert; I have two other Mosins..... I'll try what you suggest and see if it makes a difference. Do I need to worry about headspace issues if I fire it with a bolt from a different Mosin?

I took all three of my Mosin bolts out and compared the profile of the extractor with a cartridge inserted in the bolt face. The extractor on my problem bolt extended past the outside radius of the bolt. The others did not and would chamber rounds without issue in the rifle in question. With a spent piece of brass inserted in the bolt I carefully filed and stoned the outside face of the extractor until it was flush with the outside of the bolt head. Reinserted the bolt and its much improved. Still a bit tight but cycles and ejects brass satisfactorily Thanks guys, appreciate the help.... Last Edited By: Inky7 04/05/09 10:07 PM. Edited 1 times.

Most people would simply replace the bolt head along with the extractor, but then you would need to headspace the rifle. If I can fix what is there, and original to the rifle, that is the course of action I always take. I am NOT a gun smith or machinest. Just stuff I have learned on my own after playing around with milsurp rifles for well over 45 years now. Curt

It was a 1934 Tula Hex and I was about to take it back to Big 5, where I bought it. But that would entail a hundred mile round trip, so I simply looked over things and the extractor being out of place actually stood out like a sore thumb to me. It was full of dried grease, cosmoline, and dirt under it. Took some mighty powerful cleaning and boiling the bolt head to get it all broken away so the extractor could do its job. Curt

Just wondering... NRA Endowment member LECS #2

I got the rifle hand picked from Classic about a year back and it came to me clean with no cosmo. Looked as it was refurbed, liberally swabed with shellac, packed up and never issued. No cosmo soaked into the wood (stock was new, has a Ukraine refurb cartouch) which was a plus but plenty of shellac on the metal parts which was easily cleaned. I looked at the extractor under magnification and it seems new as it shows none of the wear associated with grabbing and ejecting many rounds. The extractor has a Tula star on it but the bolt head is an old Izhevsk with a bow and arrow. I'll post some pictures as it's in great shape but it's an otherwise unremarkable m91/30.
