So here is the question;

The person that pre-drilled the pilot hole for the top tang screw on my 
CPA 44 1/2 did so before the front end sides were well mated to the back of the receiver.

Not by much, off by maybe .009 so there is an annoying gap between the front of the stock and the sides of the receiver. If I take the tang screws out and push the stock forward for a tight fit, the top screw hole is ever so slightly miss aligned on a slight angle. 

This is just not cosmetic, the stock has a very slight side to side movement, not enough to call it a wiggle but enough to know it's just not right and it's not tight.! 

The heck of it is, I was standing right there when it was done, It happened so fast and before I could say stop, the person did what I was fearful of happened. At the time I didn't want to make a fuss as I did the finishing work myself. I had driven over to Dingmans Ferry to pick up what I had ordered many months earlier.

The top and bottom tangs fit great but the place where the stock meets the receiver, like I said, not so great.  

So the advice I'm looking for is this. 
Do I fill the existing miss aligned screw hole, with some sort of product fill and drill again. Or glue in a few tooth picks to take up the mis allignment or...? 
Thanks for any suggestions... I have to close the gap and get rid of the looseness.

Bob

I think I would plug the hole with a dowel and redrill.

I'm not a complete idiot, some of my parts are missing.

If the stock mates tight to the receiver with the screws out, it should be s simple matter to fill the holes and re drill. I would turn or whittle a wood plug for a tight fit, coat it with wood glue, drive it in then cut it off at the surface when the glue is set.

Wood dowels epoxied in, start from scratch to ensure tight inletting and re-drill for the tang screws. The gun deserves doing it right.

Sometimes CPA workmanship left a tiny bit to be desired, mainly during that short period when Gail first stepped down but before current folks stepped in, if you know what I mean. During Paul/Gail's time workmanship standards were premo, I trust CPA's back to those standards now.

Plug the hole.
Then re-drill.

I'd move the centered mark for the screw to the rear slightly. A few .000 is all that is necessary.
Don't move it too much or you won't be able to tighten the screw down.

That very slight off set screw hole will make the stock draw up tight to the rear face of the frame and stay there when it is then installed and tightened.

Good advice here. Be very careful off setting the hole. Easy to move it too much.
In February I received a new rifle from the new guys at CPA. Absolutely lovely in every way!

Thanks to all for the input.

I've never done any "bedding" consequently I'm currently going to You Tube "U" for my 101 course in same..

The easiest is to plug the hole and redrill.

However bedding the the stock and action into the tangs will result in a tighter fit.

Or plug the hole and redrill for the best aesthetics plus bed the stock as well will result in best aesthetics and most improved functionality.

Make sure you put clay around the trigger mechanisms and springs to prevent the bedding material seizing them up.

Make sure ALL metal that might come into contact with the bedding material is coated with a release agent.

Once you've watched Youtube videos, there's one step most videos or hot to do it's don't cover! Be sure to remove the action before you reach full setup time for the bedding compound! If by chance any area didn't get proper release agent coverage, or bedding flowed into the wrong spot, it's nearly impossible to separate the stocks from the barreled action!
I like to give the compound enough time to get firm, but not fully cured. Usually around 4 hrs. works and at that point it can be freed up, and not harm the bedding, or stop the action from being removed. You can mix up a small sample on a piece of cardboard to let it cure first and check it each hour to see how long it takes to become firm, then apply that time to your bedding job.
I had a friend bring me an M1 Garand he bedded and couldn't get out of the stock. I tried my electric heat gun, and also tried putting it in the freezer, but nothing worked. Finally had to break the stock off to get it apart. He waited the full 24 hrs. before trying to separate action from the stock, so it was well cured.

If the stock fit to the receiver and tangs is good after you re drill the holes, there’s no need to use bedding compound. If you’re inexperienced your chances of getting in trouble are greatly increased. There’s really nothing to be gained providing the fit is good.

Based on someone's recommendation, after I coat the metal with the release agent, I spray cooking oil on the entire metal area that will have bedding compound.
