Old 870 stock set on a new 870~play in the fit between receiver & butt*update:photos

Hey guys~as a winter project, I refinished a 1951 Wingmaster, "Corn Cob" stock set and mounted it to my 870P. Didn't notice any play, but I was probably too busy patting myself on the back admiring it. :) Anyhow, after shooting...I noticed a VERY slight bit of play in it and I figured I didn't tighten it enough. (though I did inspect that area of the stock, and didn't remove any material when refinishing) I removed the recoil pad, gave it a VERY tight crank with a large flat head, and there is still just a tiny bit of play there. Either the spec is slightly different, or, perhaps the walnut shrunk a little. Is this common? Have any of you ever put shims on the side of the wood where it inserts into the receiver? The play is so minor that it wouldn't take much. Just thought I'd ask.

Thanks!

PS~are additional washers under the screw head ever req.? The play wasn't forward/backward...

***UPDATE~hey guys, sourced one of these form a CGN member (thanks!) but it wasn't the fix.

In place...

But the end result...

As suspected, the fit without this part seemed ok, just some side-to-side play. I formed a fine, tinfoil shim and fitted it~no play/twist at all now. Almost invisible, but I'll test shoot it and see what happens. Seems pretty solid though. (worked hands-on in a metal shop for 7 years) Anyhow, couldn't imagine exactly what that plate was supposed to do, but I don't think it was the remedy to my situation. Any thoughts?

A 1951 stock is 62 years old. Might, I say again, might be a tick dry.
Washers are a lot thicker than 1/16". Buy a hunk of sheet brass in Crappy Tire or Home Depot and make your shim. Cuts with tin snips.

It is not simply a shim. It is a bearing plate to prevent the stock from splitting under recoil. A washer alone will not work and will probably encourage splitting.

Hey guys~thanks again for the input. A fellow I'm doing a deal with later this week messaged me saying he had an extra one of these plates, so, I'm getting one from him. Looks like a metal spacer in the shape of the wood butt stock where it enters the receiver...so I don't really gasp how it works. (metal to wood now looks very positive) Almost seems like it would create a gap between the two...but I'll report back with before/after pics.

Thanks again!
 
Seems odd that tightening the bolt didn't take care of the issue. Maybe the bolt is a bit long and is bottoming out before sucking the stock in tight?
Try some washers stacked under the stock bolt.

Is the bolt the one that came with the old refinished stock?

The bolt/washer is original to the stock, according to the guy who sold it to me. Not a huge issue, seems rock solid now....but we'll see if a dozen or so slugs changes that. lol
 
I've had to use a washer inside the stock bolt hole before. I've also had to but new bolts for the stock for one reason or another. Minor annoyance even when I lived in the North.
