People discount the 762x54 and they shouldn't because it is an accurate round in a rifle that is properly set up. I have done some reversible (in case I ever wish to sell it) accurizing to my 91/30 and with my handloads I can fairly consistently get MOA/sub-MOA with open sights from the bench on sandbags. No way I could do it otherwise. Hard to beat a Finn M39 especially when it is properly shimmed. The triggers are sweet. I have read that their barrels were lapped. My M39 is a great shooter too. Bad Ace Tactical makes a scout mount base that another M39 shooter I know uses and endorses. I do not have glass on mine.
Mosin Rebarrel
- Thread starter Wolfdog91
- Start date
I think the actions are a cast metal. Someone I know had the receiver crack shooting reasonable loads. I was at the range when it happened and he showed it to me.So I missed the hay day of milsurp modding and $60 mosins. 14yr me just couldn't convince my dad to drop $1200 for crate of them and a kr98 sniper, what can you doAnyhow I picked up a bubba'ed chopped mosin a while ago and it's just been sitting around.Was gonna make it a cast bullet/paper patch shooter but was just curious if one wanted to Rebarrel one to make it half decent for hunting what would be a good way to go as far as barrels and what would I probably be looking at as far as smithing costs ?
It's something on the back burner right now but just wondering. Thanks as usual

They are NOT made of cast metal, If it cracked it was most likely a heat treat issue and could have been one of the ones made here by Winchester, Westinghouse or Remington. Around the WW1 era and there were heat treating issues at the American Arsenals early on. I try to build mine on WW2 era action as the heat treating and metallurgy were quite improved by then.
However I do have and shoot both a Remington and a Westinghouse Mosin and have never had issues with them.
I THINK NOT

If you want boring go ahead and do what everyone else is doing, If you want unique, Build yourself one of these Mosins, They will surprise you.
Extractor mods are the easy part when adapting to a smaller diameter casehead. You mill the slot in the bolthead to make it deeper- then just carefully bend the extractor to fit (it's spring steel). The rub is in bushing the boltface as the extractor bisects the bushing, but so long as it's securely soldered in place it'll hold up to being milled when you deepen the extractor groove.
100 years ago, Bannerman did commercial 30-.06 conversions of these rifles. You can find info on how this is/was done online. They were ostensibly unsafe in the manner they done- they lopped off the threaded tenon and then cut a new one for the .06 chamber, which put part of the chamber up into the skinny part of the barrel. Obviously, this isn't a factor with a new barrel. Then ejector mod, magazine mod...
Far as flat breech, of course. In fact, I had Manson grind me a shouldered go-gage for the 54R.
In reality, there's absolutely no issue in doing a 54R breech without the extractor cut. Maybe the Russians weren't confident in their brass 125 years ago, but 54R brass has the same thickened casehead as every non-rimmed cartridge. I forget the exact case protrusion necessary to clear the extractor, but it is well within reason- IIRC around .140 or so.
If anyone here decides to tackle one, feel free to PM me; happy to share.
simple question
how do you take the oem bbls off ???

A good barrel vise, Kroil and a relief cut just in front of the Tenon face, But only if needed.
My '45 Russian M-44 has been worked on until it shoots very well, indeed. Lined the barrel channels in the stock and barrel cover with adhesive cork strips. It dampens the harmonic vibration when firing and turned a rifle that was shooting patterns into a real shooter.
I can put 5 of my jacketed handloads into a target with them all touching @ 50 yards. At 100 yards my vision is not very good, but 3" groups are my average. No scope on this one as it is still in it's original configuration.
I have also found that it shoots best when the bayonet is deployed. With it in the stored position, the rifle shoots way to the left.

Very Scientific!

Where could I get a reasonably modern Mosin bolt head? Between the world wars vintage would probably be best.
I can spend $150 at the lab that does our material analysis and ascertain the type of steel, (chemical), and the RC hardness.

You can find them on ebay and they are cheap.
There is a seller from Poland that sells new ones that are very high quality and I have bought from them and it comes pretty quick too. The parts are all new surplus most likely from the 50's.

I've got a box full of them- prolly 100 or more. Boltheads aren't dated, but some can give a broad date range if they have the arsenal stamp on them. Might even have a Remington and New England Westinghouse for the USA made ones (but they'd obviously be older)
Happy to send you a few if you like, just PM me an address.
i have seen that vid before. i have a 5 foot cheater bar and weigh 200 lbs. i could not break mine loose.
they are not all torqued the sme!

I bushed a Remington one and it was harder than woodpecker lips. A lot harder than others I have done.

That leads me to believe they are a low carbon steel and case hardenned.
This was a common practice with many military actions. The core steel has enough strength to withstand the designed pressure but is left soft to aid in ductility. The very outer layer is case hardened to withstand the “less than pristine” environment of the battlefield.
