Golly, I would suggest that you bite the bullet and look at some web articles on how to bed a rifle. There are quite a few. If you go to
www.savageshooters.com, they have educational articles -- but they are not at all the only place.
It isn't rocket science. It is merely making a "glue mold" of the action. The trick is to think it through so the glue doesn't "lock" the action -- like, by getting around a hole or something where it can form a plug.
You figure out where in the STOCK you want the glue. You use a dremel to remove some of the old stuff in those places so that the new glue will be a reasonable thickness (1/16 in? maybe, or more). You build play-do dams to stop the glue from going other places. READ AND LOOK AT THE PHOTOS.
You use masking tape to protect areas that you don't want glue to stick on the outside--when you lay the action into the gluey mess, glue is going to rise up and overflow a bit!
You use a couple coats of shoe polish on the action to absolutely prevent glue from sticking to IT.
You get some LONG screws, and cut off their heads, screw them into your action, and practice laying the action into the stock before you put any glue anywhere. Then later one, you use these same screws to lay the action into the stock. Put a little masking tape on the screws so they'll center, and also shoepolish.
You put masking tape somewhere around the barrel so that it centers in the forearm.
Usually you remove the magazine and trigger, or else you get real creative with some sort of sticky plastic to protect them, and then shoepolish THAT.
You sit back and think hard, "could anything here produce a mechanical lock???" before you do the dirty deed.
Use DEVCON epoxy putty (you can get it from Grainger.com) as the glue and you'll have 45 minutes. If you never worked with glues before, practice with some devcon on some pieces of wood beforehand.
Once you assemble the gluey mess--on some sort of rifle rest so it doesn't all fall over -- you use electrical tape or something stretchy to bind the action to the stock while it glues. The tape around the barrel is centering the barrel. If you have pillars, they are putting the action at the right height (I strongly recommend pillars).
Even if you don't do it yourself, if you read all about it, you will understand what your gunsmith is doing.
I'm a beginner and I've done two bedding jobs. The first was an all day long prep affair. Now I have a little box with all the necessary "stuff". If you're in a club, you may be able to find someone who has done it before who can coach you; otherwise, hunt for a gunsmith who knows how.
my .02 worth. You can get into trouble doing it, but if you read enough and think it through, it really isn't that difficult to do in your own kitchen.
