Bedding a mosin worth it?

Hello as you may know from one of my posts just under this one, I have a Mosin Nagant project that I'm starting. I'm fixing to order a Boyds Featherweight Thumbhole stock for the gun and I was asking about bedding. I learned some good information in that thread but it led me to another question, is it worth it to bed a Mosin? I really just want the gun to be combat accurate, I'm not some sub MOA target shooter. I would like to be able to consistantly ring our 300 yard gong at the local gun range with my newly stocked gun with a cheap couple hundred dollar scope. So with this information do you think I should fool around with bedding and bedding pillars? If I fit the new stock careful and tight will I get the performance I'm looking for? Thanks for any info.

The Mosin Nagant is a fun, inexpensive rifle that should be "combat accurate" as it stands, assuming that is does have a clean bore to start with. Even then, unless you plan to reload, you'll find the available surplus ammunition lacking in high accuracy. At the risk of sounding silly, how big is your gong? Anything over 9" or so should be at risk, as it stands.

Personally, I wouldn't invest much in improvements to a $100 rifle, but use it as is.

Im not investing money in it to make it more accurate. Its just a project to keep me busy. I like the look of the boyds stock, plus they are cheap. Cheap gun, cheap stock, and cheap ammo equals fun for me. Our 200 and 300 yard gongs are 16 inches in diameter.

In that case, spend away!! Everybody needs a winter project.

So you think I'll be accurate enough without bedding the gun?

How does it shoot now?

If your bore is in good shape and you have decent(surplus) ammounition your Mosin should still be able to hold 3-4" groups at 100yds. Triple that for 300yds and you see where I'm going with this.

Mosins in good condition can usually hit 1-2 MOA all day long with good ammo. Some can do better. While I haven't heard of anyone bedding a Mosin, one thing that works well in the default stock is to cork the barrel. That is, get a thin strip of cork and put it between the upper handguard and barrel. This is a trick that's commonly used to eliminate looseness in the upper handguard (caused by the wood shrinking over the years), but it also yields noticeable accuracy bonuses. It's effectively a poor man's bedding job. I'd expect similar results out of proper bedding.

Just did this project, you need to sand down the stock from the barrel base to the end and sand out the handguard until paper slides, than take some gasket cork and cut 4 1in long cut them wide enough to fit in the stock nicely, place the 4 pieces where they are over the top of each other right by the barrel clips ( which are pressure points) than torque your screws. My mosin now shoots a 5 shot 1.2in group at 100yds. Anymore questions shoot me a PM.

As has been said any improvement (and worth thereof) would depend alot on how it shoots now. I'm curious does the Boyd's stock have the 'upper handguard'? I doubt it does but didn't know for sure. If not you could try free floating the barrel first by sanding out the barrel channel and/or possibly shimming the action. With how thin the Mosins barrels are this seems to work great for some and not so well for others probably due to the barrels natural 'undisturbed' harmonics. If this didn't help I would then 'cork' the barrel as gunnerboy mentioned. Detailed descriptions, pictures and results of this project can be found with a simple 'corking a Mosin' search.

Best of luck and keep us posted!

No upper handguard on the boyds stock, and its supposed to free float the most of the barrel. I think others have stated that maybe a couple inches only touch close to the receiver. Here is the stock itself:

If I get a second Mosin I would love to get a stock like that for it. I love the feel of thumb hole stocks but don't actually have any yet. The Mosin I have looks too good and shoots too well for me to mess with it.

December 3, 2012, 12:35 PM
yea I probably should have saved the one I have and did the project on a different one. I still want to buy another to keep in stock form. I traded a hi point .380 for the one I have now, I think I got the better end of that deal, lol. Those stocks are pretty nice for the price tag huh?

If the Mosin is in good condition, functions and shoots well you may have. I haven't actually put hands on a Boyd's stock but from reviews I've heard and articles I've read they seem GREAT especially for the price tag.

It is almost always not worth glass bedding, but I do it anyway.

I glass bedded and pillar bedded this Mosin Nagant in 2004.

I glass bedded a Mosin Nagant in 2011 and relieved the stock and pillars to make room for a Timney trigger, which if you have the bucks, makes for a good safety.

I hope this works and helps......... JUST finished mine, still have to add photos of scope mount and such.... haven't even been to the range yet,...

I am currently working on the same exact project. I will not be getting the Boyds stock though. I have an original laminate stock on it already. Refinishing the original stock is going to take up a lot of time as well. Plan on doing the timney trigger, bedding, parkerizing, stock refinishing, cutting off the sights and getting a decent scope, rocksolid industries make a good bent bolt for it that I will be putting on it. I dont typically take on a project with this much detail but i think its a good cheap gun to work on. Good luck on your project!

Heres a trigger spring i did, and the cork bedding.

thanks for the pictures. If my new stock free floats the barrel, do I still want to use the cork out on the end of the stock? Or would it be best to just leave it floated? I'm definitely going to run some cork gasket on the receiver end of the barrel where it does touch.

Gunnerboy

No you do not need any cork on a sporter stock, what you do is sand down the stock until you can slide a dollar bill from end until the fat portion of the barrel

Very few Mosins shoot below 2" MOA and that exceeds original specs. It can't hurt anything to glass bed the receiver. I have used cork bedding and shims with good results. The Mosin barrel gets very hot real fast and it affected by harmonics which is why the groups string out. If you do glass bed the receiver I would still cork the barrel and not free float. They are cheap rifles and fun to play around with.

Why would corking be better than free floating? I thought free floating was the be all end all. Also since the mosins generally aren't that accurate I don't think I'll be bedding it. I am still open to using the cork gasket in any way possible if that will improve the gun though.

Harmonics and heat allow the barrel to move around. I have better results with corking. The Russians also did something similar to corking to improve accuracy. The barrel on these things are thin in comparison to the round.

Wouldn't the cork contact also tamper with harmonics? If I do use cork should I just cork both ends of barrel like in gunnerboys picture, even though Im using a boyds stock and not the original like he did? Also how tight do I want that cork in between the stock and barrel? thanks

The cork acts basically as what a bull barrel does, with the military stocks the cork is a cushion that squeezes the barrel when the handguard clips are put on which in turn makes the harmonics move the same everytime which makes more consitant shots

JBrady555

but my stock doesn't have a top piece, its a boyds thumbhole stock, so there won't be any squeezing the barrel in between the top and bottom stock pieces. So would I still be better off corking underneath the barrel? Or should I just free float as much of the barrel as possible without cork? If cork is recommended for the bottom, how tight should the fit be? Wouldn't too tight put too much pressure on the underside of the barrel effecting accuracy also?

Agreed.
You may have to play with it to find the sweet spot(s). Supporting the barrel at the receiver and just in front of the front sling holes is where it's normally done.
You can get a roll of rubberized cork gasket material from Autozone for around $5.00

I bedded original Finnish Mosin Nagants in their military stocks. I did not pillar bed, I just routed enough wood to form a 1/4" thick bedding layer.

I did not play with barrel corking or barrel fit in the barrel channel.

Overall it made the groups circular and the groups did not move as much when I changed bullet weights.

I was actually surprised on how well Soviet Nagants shot even with the receivers bowed by horrible bedding. I bedded some of them also.

Accuracy will be limited by barrel quality.


Back in the 80's C.E Harris wrote an article in the American Rifleman on Mosin accuracy. He changed the service rifle barrels to custom barrels. The rifles shot better, on a par with 30-06 rifles as I recall.

Stock just showed up. I layed the receiver/barrel in the stock and took this crappy cell phone pic, but here it is. The stock still has some spots where I have to sand or dremmel so that the receiver sets all the way down in the stock. The fit is too tight now for the stock to fully accept the receiver.

If your going to bed a Mosin, few things you gotta do first.
Get the Soviet Union National Anthem playing on the stereo to bring out the pride.
Few bottles of Vodka to loosen things up and get in the mood......


OK, with your Boyds stock I wouldnt be worried about bedding right now.
Get things to fit correctly, make sure the barrel is free floating, then take it to the range and let her roar.
Accuracy problems try handloads or different bullet weights
How is the trigger? I busted the trigger sear/bolt spring on my M44 and replaced it with a NOS Finnish sear/bolt spring from crsurplusspring.com and I am quite pleased with the result. smooth trigger pull all the way to a clean break and zero trigger slop with the bolt cocked or not. If you dont want to spend the $16 you can do the trigger mod that accomplishes the same thing: shim the sear/bolt spring and add a trigger spring to remove trigger slop, cost you a soda can and a spring from a stapler remover or bag clip. plenty of vids on youtube showing this mod.

still have problems then I would look into bedding the stock and if you go that far might as well pillar bed.

Keep in mind these rifles are combat accurate, not sub-MOA competition accurate rifles. Altho Caribou has some wicked videos of the hunts he does with his Mosin. Check those out.

Thanks for the info. I just started another thread close to this one dealing with the fit work. I've got pictures in it too, when you get a chance I'd like to get your input over in that thread too. This is the first time I've fit anything other than pipe and boiler tubes, lol.
