does anybody have information on the manner the armourers shimmed these rifles before the postwar refurb?im sure theres a barrel or two of shims swept up after there shifts out there some where.ive tried the cartridge box shim trick but it isnt original or consistant.it will tighten the grouping for only 10 or 20 rounds.there must be a manual from those days of development that instruct the armourer on this setup before they issued them,or front line reports to that effect.i have scoured the net and even wrote the tula factory in russia without success.accurized these rifles should group a five round clip as tightly as a C1 .

This might help. If you can read Cyrillic. Unfortunately there isn't much that can be done to accurize an SVT aside from the Shimming method you already tried. It's one of the main reasons the sniper variant was never very popular and discontinued early.
I'm sure when svt1940 himself gets here, he'll have something to suggest though.
Try the shimming you did with the cardstock, but substitute aluminum flashing or other thin aluminum material. If you use a popcan, it should work, but you'll probably end up using 7 shims.

ok what "shimming" are you talking about?
I assume you mean shimming at the rear of the stock so the receiver cant move back and forth in the stock? Depend of the thickness you need, i would suggest a piece of sheet metal,the kind used to do body work, aluminium(like a piece from an old ladder) . I would try gluing it with epoxy then with a file, you could file to reach the proper fit you need. Brass shimming material could also work is you can find, in severals thickness ideally. I never played to shim my SVT's yet but if i have too, i will do like i said.

im going to try to translate this info from steamingpile maybe upload it to google docs and use the translate option.these rifles will shoot one hole at a hundred,as long as there not heated up,the barrel is bedded i just before the cross pin wth bedding compound and a small wedge of hardwood tapped in from the bottom where the trigger assembly fits,lightly tap the wedge where the reciever meets the stock to take up the slack,pushing the reciever firmly against the crosspin,not excessive enough to bend the pin but enough to keep the rifle from banging around from recoil,you can add another if your group wanders again,i allso found there is play horizontally between the rear tab of the trigger assembly and the stock for sure on any refurbs with avt40 stocks(dual slots carved in the stock by the safety) have bent my pin on my experiment with plastic as there is no give,good thing i had another.shimmed and accurized these were a trophy shooter from the bit of info i gathered,not a rifle for the average boris on the frontline though that seems to be a mistake that the russian army realized early and corrected by changeing the standard issue back to the mosins.but im sure you still cant beat the solid platform the bolt rifle gives you,but in 1939 when they introduced svt40 there must have been merits that put this rifle up as there sniper issue.im going to look at trying some proper bedding for the barrel but that rear reciever will have to be tigtened before you put the trigger group back on as there just is no way just dropping the reciever back into the stock could be tight to much tolerance between wood and metal,this im sure was one of the design flaws that are mentioned in all the info i could get on line,nobody ever explained it ,maybe i have
