I was stripping and cleaning the barrels of both my M91/30 and my M44 earlier and set the bolts right beside each other. when i put them back together i couldnt remember which was which. well i just picked one and put it in the 44 then procceded to put the other one in the M91. It wouldnt fit. so i switched bolts and it fit perfectly. I find it odd that the M91/30 bolt fit in the M44 but the M44 bolt didnt fit in the M91/30 since they are supposed to be the exact same rifle other than the M44 being shorter

each bolt is machined and matched with one particular gun, thats why if u change the bolt u must have the headspace checked before firing that firearm

I would assume both the bolts don't have serial numbers on them, or it would have been easy to tell which one belongs to which rifle. Anyway, that is weird. They should fit on either. What I have noticed that can happen sometimes (in mine) is that when I am inserting the bolt back into the receiver the bolt connector gets misaligned with the bolt head catching the side of the receiver. But I do have some Mosins whose actions are not as lose as the others.

When these gun were re-worked, they were often stripped down into piles of parts. When re-assembly was started, the armorers would just grab parts out of the pile until they found a part that would work. This is one reason that so many of these have mis-matched numbers. you also need to keep in mind that this laso occured during wartime conditions and machining tolerances were often off the charts-if it went "BOOM" it went out the door. This is actually pretty common with ALL military guns-parts may or may not interchange due to machining variances.
