Nagant that the bolt has trouble decocking using the trigger, but if I put a different bolt in,it has no trouble. Is something wrong with bolt? Its a m91/30. Any ideas?

That's kind of a vague description. Can you give more details of what you are doing, and what the bolt is doing, or not doing?
A. You have closed the bolt and pulled the trigger to try to dry fire the rifle.
B. With the bolt open you pull, and hold, the trigger and close the bolt to relieve tension on the striker spring.
First determine if your rifle is numbers matched. This is a safety precaution as bubba may have installed a mismatched bolt giving no thought to safe headspace.
This will show what you are looking for.

Next you need to disassemble the bolt and give it a thorough cleaning. There might be a buildup of cosmoline or crud causing the problem.
For scenario A. Inspect the engagement surfaces of the sear and striker for burrs, galling or file marks (someone may have tried doing a bubba trigger job). Also check to see that the safety is disengaging completely.
For scenario B. Inspect all camming and locking surfaces for burrs or galling.
A simple cleaning may remedy the problem. If any parts need replaced, have a competent gunsmith do the work. Replacing parts may cause an unsafe sear or safety condition or excessive headspace.

Asphalt: if, I push the bolt all the way forward, push the handle to the right just a little without closing it, then pull the trigger, it should decock the bolt (I read that's the way to do it) however, it doesn't decock it. If, I take the bolt out and use one from one of my other mosins, it works everytime. I am fairly new to the mosin rifle, so I'm not sure what's wrong with the bolt? It is #s matching except the bolt and does not appear to have any bubba job done to it. When I received it, I disassembled the rifle and cleaned all the Cosmo out of it, oiled it, checked the action and all worked fine.
Scenerio B you describe sound spot on, but the bolt closes automatically when I pull the trigger instead of holding the trigger and closing the bolt myself. Do you know what I mean?
Clear as a bell Rage.
Will it close easily if you hold the trigger and close the bolt manually?
Also, try temporarily installing the striker spring from one of the good bolts into the troublesome bolt. The issue may be a collapsed, (weak) striker spring.
That massive cocking piece allows the shooter to lower the firing pin by pulling the cocking piece back off the sear, pulling the trigger, and then letting the pin/cocking piece to move forward .
It goes without saying the chamber should be empty
Swap out the pin and cocking piece into your original bolt and see if the problem goes away.
One poster mentioned a safety. You CAN pull back the cocking piece back and rotate it to the left to engage the receiver wall, but there is no actual safety on a Mosin.
