Question about accurizing a Mosing Nagant M44

[Matt Dillon]

Friends:
I have an M44 that has a tendency to have vertical stringing, in that the first shot from a cold bore is ~ 4" below the bullseye, at 50 yards, and as the bore warms up creeps up the target until the POI is in the bullseye.
One of my boys wants to take it hunting in a few weeks, and I'd like to see if I can accurize it to fix this most frustrating issue. I have seen some videos on YouTube regarding sanding out the stock underneath the barrel,and only having the stock touch the barrel at the end of the stock, where the upper stock and lower stock end up.
Does anyone have a resource to point me toward for more specifics? Would I need to remove the action screws from the tang, and underneath the rifle to accomplish this?
Also, I have heard that putting some epoxy bedding material in specific locations may help.
Again, does anyone have a resource that I might read to understand how the bedding process and stock sanding process works? Thanks so very much in advance for your help!

You can use cork packing material to increase up pressure on the barrel and help keep it from whipping around. Check out the lee enfield accurizing channel on youtube. I know they are not identical but lots of good information there.

As AK47TIM said corking the barrel should help. I have done this on several. Also remove the extra weight of the bayonet from the barrel before trying to re-sight rifle. You can always put it back on. Before you cork the barrel you should make sure the barrel channel doesn't come into contact with the barrel.
The round you are shooting heats up the barrel quickly. Shoot 5 rounds and let it cool off some.
Check You Tube. There are a few other tricks to help out.

I see this cork method brought up a lot. Does a fella get big differences with humidity/moisture?

I used some heavy felt material with some oil in it, worked well on my 91/30.

But bedding the action (mainly just the recoil lug) and adding pillars helped more than anything on mine, it was good practice on bedding a rifle and I had already "destroyed" collector value on the gun when I tapped the receiver for a scope. I know people say Mosins aren't worth the expense, but it cost me maybe 10 bucks to add pillars and bed the action. Used JB weld and .... i forget what I used for the pillars but it was something from the hardware store that i cut to length for a couple bucks. Using Prvi ammo it shoots 1.5 inch at 100 yards. I also shimmed the trigger spring, but be careful doing that since the safety sucks on the Mosins.
