Every one of my Mosins exhibit this symptom and they are all squeaky clean. I believe even the Russian field manuals noted the proper way to open the bolt after firing was a firm upward slap to the bolt handle.

Well, given that the base diameter (not rim) is almost the same (0.489 for the MN, 0.505 for the 45-70) the major factor of bolt thrust is then pressure.
The 7.62x54R runs at 57,000 psi, while the 45-70 goes to 28,000 (SAAMI specs) That gives the Mosin 3,407# bolt thrust vs 1,785# bolt thrust for a 45-70. Between just over half the bolt thrust and better QC on cutting the chamber, I don't forsee any issues opening it after a shot.

No problem, and don't ever hesitate to warn me that I may have overlooked some issue somewhere. I'd much rather be reminded 99 times of something that I was already aware of than to overlook that one important detail that could be the difference between a good shot and a ka-boom.

You very well could be right right Czubek. But I don't have any idea what the "fork end of the connecting bar" is. I do know the bolt handle is too short to provide much leverage. Considering it's a cock on opining action, and a rimmed cartridge which is harder to extract and a really short bolt handle, it can be rather hard to work the bolt some times.

I own 2,a 1929 (I think) 91/30 and a 42 M38 with a M44 lammy stock,,both bolts seems to lock up on em too,I actually tried what Brian is describing with the bolts and it seemed to help,I took the bolt apart on my 91/30 accidently at first and cleaned it very thourghly and that also seemed to help,they were very thick with grease and I cleaned it all out and sprayed silicone lubricant on it instead,problem solved,,at least for now,,ok rifles I guess but I would trade 10 of em for a Swedish Mauser,,20 if the mauser had a tiger striped stock

Gotta be Russian about it when working the bolt.

I have virtually no action issues when using Winchester white box. Silver Bear is a little tricky, and Wolf is a bieoch to open the bolt up after firing.

Yep,I got the mosin cravings , dont know why? just pick one up at the gun show last week, it felt good. Then I started doing my homework and study on em, now I cant stop. Felt like an old kentucky long gun when I picked it up. the dealer at the show let me go thru the 10 or 12 boxes he had. I pick a 1939 91/30 Tula, round reciever mainly looking at the wood grain of the stock, now all the hisory behind those old Dragoons has got me hooked. I may have a couple more before my curiosity subsides??

Good for you Harry, they are a good rifle, they were built for Russian peasant troops. They are very simple and robust. The 7.62x54R is in the 30-06 class. This round is still used today in belt fed machine guns and Russian sniper rifles. For a round introduced (if I'm correct here) in 1891, that's a pretty good career.
