I dont need to but If I did need to how would one go about removing a glue in from its stock other than a sledge hammer of course
Heat.
epoxies let go at fairly low temps from 200-400 degrees??? (I'm guessing here) but do know that I've used a torch (VERY carefully!!!, too much heat available) an iron and a heat gun. I'm sure that there are other ways. Not too far after "too hot to touch" the glue starts melting, just lets go.
My technique is always to jig up such that you're applying constant separation pressure to the parts, maybe put the barrel in the barrel vise and hang something on the front sling swivel stud or tape a weight to the forend or whatever...... and something to CATCH the stock....... and begin applying heat from the front of the action to the back so the pressured areas release first..
It's easier to DO than to describe

Most epoxies start to degenerate at approximately 212.5 deg.C
Make a smal wedge to go between the barrel and forearm of the rifle applying some pressure and set an iron (turned on of course) onto the scope bases...when the time comes there might be a small puff of smoke...or not, but the pressure will seperate the two items.

The opposite way
The opposite way is to use cold - dry ice. I like this better than the heating method, because it avoids problems with damaging stocks, paint, etc. Dry ice works well because the cold metal shrinks and cold epoxy gets brittle.
Lay the rifle on several blankets, cover the action with dry ice, & wrap the whole thing up with more blankets, quilts, etc. Let it get cold for a few hours.
Then take the rifle out & give the under side of the barrel a sharp hit with a plastic or wooden mallet. The action will break free, leaving the bedding in nice condition.
Dry ice can be bought in "pellets" but you might only be able to get big blocks. The blocks can be broken with a hammer to more manageable sizes. If you really want it crushed, wrap the baseball sized lumps in a towel & hit it against a cement floor or use the hammer again.

Thanks Ive bought an older Benchrest gun , After I get tired of making 6ppc bullets I plan on using it for a varmint rig & may want to take it out of the stock, rebarrell, or what have you, any way Ill probably make a bolt up out of it for convience sake, I would like to leave the bedding in tact so ill probably try the dry ice, the iorn sounds easy but dont know how the bedding will look after that?Seems the dry ice & the wedge under the barrell would work well

With any luck the guy that glued it in did not prep it properly. If he did best bet will be an overactive end mill.
The dry ice may work, but I would be afraid of more likely to damage the stock since extreme cold makes all materials brittle.
As an aside, I remember an episode of Orange County Choppers where they were desperately trying to remove a gear from a shaft without having to remove the motor (the bike was to be unveiled that very day ...and they have to be functional) and someone recommended to freeze the stubborn gear with nitrogen. As someone who worked in cryogenics for a few years, it was more than amusing watching these world renown custom builders using a tank of gaseous nitrogen with a blow nozzle attempting to super-cool the offending part. In the end they realized that liquid nitrogen was the medium they really needed, not the easiest item to round -up on the fly.

Glue in
If you are only planning to remove the action to rebarrel, it really isn't necessary. Benchrest shooters remove and install many barrels to the same action without ever removing it from the stock. I hate to separate a glue in unless I have reason to believe that the glue is failing.
