I have been thinking of starting to do some work on one of my stock mosins, Nothing to crazy. I plan to polish the bolt and was thinking I might glass bed the mosin. I am wondering if the glass bed will really help with my accuracy at all for a rifle like this and is it really worth it.
Glass bed a mosin worth it?

First off have you shot it and are you pleased with the accuracy ?
If you answer yes to the last question, leave it alone and enjoy it !
Most Mosin Nagants will surprise the hell out of you regarding accuracy. Handload for it like your loading for a medium load 308 win. or 303 British with the right sized bullets.
Tuning and polishing by hand cost nothing but time and gives you a sense of satisfaction you are ahead of the game.
A good bedding job never hurts !

I am pretty happy with the accuracy before it gets warm. Once it heats up it can get bad. Is there a possibility of making it less accurate if I bed it ?

I haven't heard of accuracy getting worse after a good bedding job, you are just providing a more stable platform for the barreled action.
Yours sounds like the barrel is moving from the heat usually caused by no stress relieving of the barrel during or after boring and rifling. During WWII match barrels and stress relieving barrel were not a priority but building fast and in major quantity was.

Discrete glass bedding will help. If your stock is impregnated with preservative in the ways you may have problems getting the bedding to adhere.
If you find your rifle is having accuracy issues once it heats up, you have two options. One let it cool down. Shooting any rifle quickly for a sustained time period is detrimental to the bore and seeing as you aren't shooting under stressful conditions you might as well be nice to your rifle. Two, if you are talking about opening patterns after 3-5 shots you may have bedding issues at the receiver but more likely along the barrel channel. Disassemble the rifle and using a candle, blacken the outside of the barrel all around. Then, very carefully reassemble it so the barrel doesn't touch the fore end of the stock other than the forward pressure point. Take it out to the range and shoot it until the group starts to open up then shoot a couple more rounds so you have a good black mark on the wood where the hot barrel has caused it to warp and come into contact. Very carefully disassemble the rifle again and with a dowel and coarse sandpaper clean up the offending areas. Repeat this procedure until the assembled rifle settles down. Be very careful not to sand off the fore end pressure pads that are there on purpose.
About ten years ago I witnessed a couple of groups fired by a fellow that had sporterised a nice hex receiver Mosin. He had picked up the rifle and the factory sporter stock form International back in the early 90s. The rifle was already assembled as a sporter when he purchased it. Somewhere in the US he had found a strange looking scope mount that was attaché both to the side of the receiver and on the top flat. It was cast iron and very nicely done. The scope was an old K4 Weaver. The rifle still had its original length bbl. When he was finished shooting some very decent groups that were about 1.5 moa with factory Norma ammo I asked if I could look over his rifle. He was a very nice fellow and handed it to me. It had a beech stock with a pistol grip and the fore end went past the tangent sight about 12cm. The stock was about as plain as they come without checkering. The one thing that was notable was that it was free floated from about an inch from the receiver. By the way, the bore on this early model 91 was almost perfect. It shot very well.
All of my Mosins, Russian, Finn, Westinghouse, Hungarian, Chinese and Sig shoot very well as is. Especially the Soviet 91/30s with laminated stocks.
The Finns found out early that the Mosin stock wasn't always good and many of their stocks have been assembled in two pieces with finger joints just after the reinforcing bolt.
Considering the age of these rifles I am very surprised at how well they shoot. It is a testament to their builders, often under extreme conditions.

Not really sure but what is glass bedding? What does it consist of?
I have a few Mosin Snipers, One I like to take to the range and fire from time to time. When I have not loaded anything that week. The other one I keep for collector purpose because of it condition and that its all matching. The shooter sniper makes great grouping at 100yds with milsurp ammo, and after about 20 rounds they float a bit but still within 4". You can sear your hand if you touch the barrel after 20 rounds..lol

Why would you want to abuse a barrel by getting it so hot that you could cook a pound of bacon on it.
Perhaps in a sustained fire fight where your life depended on keeping the hordes pinned down.
Glass bedding worth looking up on Google.

I don't even think abuse, I am thinking about a great grouping at 100yds, not thinking twice grab it by the barrel and the feeling is like putting your hand on a stove element that has been on for 5 mins. It shrinks back to normal after 10 mins. Its lasted 70years thus far and no plans on the agenda to retire, that sniper is one tough cookie
