Mosin factory shim question

[headoftheholler]

Just picked up a '43 Izzy 91/30, no signs of Finn capture or ex-sniper. Straight to me in the Century box so whoever did this was in Russia. So how unusual is it to find shims on Soviet mosins? There are two shims in the stock on top and two on the bottom. Metal looks like galvinized tin? Why would they have shimmed it?

Poor stock fit

I have seen articles where the Russians used strips of copper to raise the receiver and float the barrel but not galvanized.

The galvanized metal is from an ammo tin. Russian WWII ammo came in galvanized tins 2 to a crate and very sloppily solderd.
The factorys in Russia only shimmed Sniper rifles.
It was most likely a field armour's job, not factory. They did small repairs and getting a stock to metal fit proper is one of those repairs.

Do you have small holes, likely filled along the recivers left side or on the forward end of the reciver? and filled or repaired wood alongth eleft side?? If so, it would be an "Ex-sniper" and the shims were the factoys doing. They are most noticceable along the inside of the action with the bolt back.

regardless, do not move or lose them, they help with accuracy, and if someone took the time to shim the action, then you most likly have a rifle that is noticably accurate, with proper ammo and shooting skills, of course, added to the equasion

Bubbanisky probably.

Definitly not an ex sniper, double checked when I saw the shims. Ive got a M44 ahead of this one , very curious about accuracy though with the shims. I can also post pics tomorrow if anybody is interested. Since this came direct to me from Century I highly doubt an American bubba'd it.
