The Mosin Nagants all had this problem,in the 2nd world war as well,both the long rifles and the carbines...when the Soviets introduced the Mosin Nagant,they were looking mainly for a cost-effective,simple to clean and maintain,while providing their infantry with a weapon to combat the Winchester repeaters that the Turks were using at the time (I think it's the Turks,don't quote me on it)
The problem with using a cost effective design is,yes,you'lle run into stupid little problems like that,the way I've combatted this,is closed the bolt until I felt it stick...then oiled and scrubbed the area ,and worked it...it still sticks,but not as badly. The Russians,to counter the sticking gave the bolt a rough slap to knock it free,I wouldan't recommend that as you may damage the bolt and/or the reciever. This is assuming that,you are talking about after you fire,when you wish to eject the spent casing...if it's "Jamming" when you are going to re-cock it...again,alot of Mosins have that problem,but as stated by another member above,I think that a good cleaning,and decent ammo would help,not fix,but help the problem...But from my experience with the Mosins,this is a common occurence and theres really not much,aside from oiling it to death,you can do about it.
Also,the condition of the bolt/breach itself could be the problem,is it pitted? scratched?..are all of the surfaces that the bolt comes in contact with damaged? all those things would be a factor as well..
