My 91/30 bolt seems loose. It feels tight enough lengthwise, but it doesn't take much effort to lift the bolt handle.If I hold the gun upside down I can open the bolt with 2 vigorous shakes. Does anyone else have a similar issue with the bolt?
 
One of my M38s is similar but not as bad. It should tighten up with a round loaded in the chamber.
 
EL34/6L6 has the right idea.

See if you can find some 7.62x54R snap caps at your local gun shop. Chamber one and see how it feels then. If it doesn't tighten up with a snap cap in it, then you might need to have someone take a closer look.

You can use a spent case if you can't find any snap caps.
 
It seems to be the same with a round in the chamber. I installed a new 30lb firing pin spring but that did nothing. All the numbers are matching too, so I wouldn't think the bolt is mismatched.
 
Do you have a second mosin? If so, swap the bolt heads and try the gun with the second mosins bolt.

Things also tend to tighten up after firing a mags worth or two of rounds.
 
Unfortunately I only have the one. I've fired about 50 rounds with it so I don't expect it to tighten up now. I'm just having second thoughts now whether it is safe. Otherwise it seems to function fine, I'd just rather be safe than sorry.

I wouldnt worry mosins are about as strong as it get. All #### on open bolt actions rifles are designed to close the bolt as the firing pin drops. So even if its open a little the firing pin will close the bolt.
 
mY m44 is also quite loose but they will still function fine as there tolerances are ment to be very slack. you can do as mentioned before try a bolt out of another gun but you may just fine the same feel.
 
They are meant to be loose, but it does not really matter because of the forward locking lug design. The only thing to watch for is to make sure there is not so much vertical movement at the back of the bolt that the cocking piece can be lifted off the sear allowing it to fall. You can check this by closing the bolt (on a snap cap, dummy round, spent round, or empty chamber .... stating the obvious I know .... ) and then GENTLY pry up on the bottom of the cocking piece, not forcing it mind you, just until you reach the end of it's natural play. Then bang the butt on the ground a couple of times, slap the stock a bit and see if it falls. I am thinking about the only way it would is is someone had filed the top of the sear trying to lighten the trigger pull. Or if the sear spring had been bent out of shape or something like that.
