Boyd's...
Idlfh 7--I too have had really good experiences working with Boyd's Stocks. Strongly recommend that you (1) plan to glass-bed your receiver, and (2) buy the Boyd's stock "unfinished." That's Boyd-speak for not varnished nor finish-sanded; the inletting is all done, and done well.
You Dremel out the stock, around the recoil lug and the tang, coat the receiver WELL with release compound, put in the glass-bedding compound, put in the receiver, let the compound set, and voila! your stock is custom-bedded for your receiver.
Then you sand. And sand. And sand--it's the most tedious part of any woodworking project, but necessary for decent looks. You can also make any small alterations to the outer contours of the stock, that might please you, during the sanding.
Then you put on 3 or 4 or 5 coats of finish. I've used plain hardware-store satin spray-can spar varnish with good results. Lightly sand between coats. BTW, you do finish the inletted part of the stock--gotta seal out the moisture.
My project took me an hour a day for a week, or so, and then 1/2 hour/every other day for another week during the varnishing.
The 'phone people at Boyd's are used to talking newbies through the process--very helpful. You can get glass-bedding kits and finishing kits from Boyd's, but I used a Midway glass-bedding kit, IIRC, and sandpaper and varnish bought locally.
NOw--Accuracy improvement?? Only if your original stock was negatively affecting accuracy. Your accuracy will not be degraded, unless you REALLY screw up your glass-bedding. Looks improvement?? 100% at least!
Tell you what, though: I'd do a "practice" rifle first. Myself, I glass-bedded an SKS in a cheapo plastic stock, before doing my Boyd's project. Figured if I wrecked the whole thing I wouldn't feel too badly about it. But, nothing went wrong, which greatly encouraged me to proceed.
Whatever you decide, good luck on it, and please keep us posted. With pix. We all like pix.
