bedding and shimming

[Oddball]

does anyone have a good step by step video of pics to show how to properly shim a 91/30? and does anyone know how to free float the barrel using cork? i read about using cork on a website somewhere and they said its good cuz it absorbs the vibration. Im just trying to find small things to do too it, i already upgraded the firing pin spring and addded a trigger slack spring and i also order from a guy on youtube a front sight post.

Welcome to the forum, I don't know what videos on the subject are on youtube, I never searched for them. My Mosins that are shimmed came to me that way from Finland, there are a few guys on here who have experimented with bedding using cork. Off hand I don't recall who, but maybe they will pipe up if they see this post. Keep in mind that all this will only take you so far, these are 70+ year old refurbished war rifles, they have wear on them, and were not built as precision marksman's tools in the first place. Acceptable was 4-6 MOA at 200 meters, or minute of man as the saying goes, they can be improved, but don't expect 1-2 MOA out of the average refurb no matter what you do to it.

I found plenty of information by doing a search "Mosin Nagant shim bedding". Some of the information I found appeared to be translated from soviet documents...original sketches. My non-sniper '42 Tula grouped about 6" at 100 yards. By shimming I got it down to about 3" so far.

My barreled action.... just setting in the stock could be rocked back and forth and up and down. The recoil lug on the receiver was not seating firmly against the stocks recoil bolt. I trimmed up a thin piece of sheet metal to close that gap. The receiver was making good contact with the stock at the front action bolt but the tang on the rear of the receiver was way off. I shimmed that up with a couple of thin shims I made out of a copper sheet. I made sure that I could slide a dollar bill under the the barrel along the stock. The last thing I did was wrap a single wrapping of old fashion friction tape about 3" in length around the barrel at the front handguard band.

Still tinkering with it. It is fun to tinker and learn. It is a slow "trial and error" process...but fun and rewarding. I think I'm as about close as I can get right now and dont expect much tighter groups until I start working on handloading my own cartridges.

These are a good start

I just corked the barrel under the front cap and shimmed the front of the receiver (in front of where the metal post with two pieces of plastic like from a plastic container from scissors or other plastic container when you buy some product.) That free floated the barrel..I don't really like all of the cork under the barrel idea. Just shimming the receiver in front and putting cork under the front end cap works very well for me....check my target.

You could try putting a piece of cork under the front barrel cap. I free floated my barrel shimmed the receiver and corked the lower front cap. I gave 1 1/4 " groups at 100 yards...These gun are VERY accurate.
