could a mosin nagant barrel be used/fit a enfield no4mk1 receiver.

Is the Enfield action strong enough for x54 ?

Many Longbranch #4's have been converted to 7.62 Nato as target rifles. The 7.62 X54R runs about equal pressure so shouldn't be a problem.

I've been thinking about this conversion for some time, as the Russian ammo is inexpensive...for now.
 
don’t waste your money , most of them never worked properly. stay with the 7.62x54r they are much better.

Oh really? Thanks for the tip!! Being 303 was the deterrent for me, nothing against 303, just not interested in loading for a rifle I would rarely use.
But I'm also guilty of owning rifles I never use heh heh.
 
I found it more had to do with heating up, then actually the cases. If I pop thru 5 fast, more and more I do that the harder the bolt is to open, but if I take my time, seems like its not as bad.

This^ I can't count the number of guys I've helped (or tried to help) after they've ripped the stuck case. This always occurs after much swearing, beating and sometimes bleeding from fingers/knuckles torn up in an attempt to get the bolt open. Wanna ask why I don't own one? Lol! ;). (pitted, rusted, dirty, or other wise out of spec chambers is also an issue...polish is your friend if that's the case.)

I also understand the gun tinkering just "cause I can...and I think it would be cool to have the only..." However, the OP seemed to be looking for a solution to his hunting rifle woes. Anything can be accomplished if enough $ and time are invested, but I didn't get from the OP that that is where he was coming from. I don't like the MN due to ALL the problems I've seen others go through and would take my Enfield's any day over the Russian contemporary, but if it's a rifle he wants and one is pooched, either replace it (another Enfield) or shoot the MN he apparently has. That's where I was coming from in my last post.
 
all this or...you could just put the sporter LE to pasture (she's done her duty), and just shoot the MN as is? (hideous action and all). With the money you save on x54mm vs. .303Br you can invest in a nice hardwood billy bat to wack open the action on the Nagant saving broken boot heels or bruised hands. :)

there is either problems with your mosin(stick bolt ect) or problems with your hands comrade :p
 
maybe if the op wants to play around a good .30 cal mg barrel could be had and then you can just load using .308 or .309 bullets of course there's also take off barrels that can be had for cheap
 
Not looking to fix my hunting rifle.. its just an old junker of a no4 i picked up. More or less just something for me to tinker with On the slow nights .i have a good sniper mosin a fin capture mosin and a fullstocked smle.. not sure where all the speculation and theroys as to why i want to do it. Like i said just a crazy idea because ive got a bunch of crap laying around and why the hell not?

Turn it into a 32 ACP or a 45 ACP..
 
I know a guy with a lathe who could trim a mosin barrel down to size, is barrel threading something i could get done by any place capable of doing it? Or is there anythng special about rifle threads?
 
Lathe cutting threads is a standard operation.
The barrel must be properly fitted to the receiver. The chamber must be reamed. An extractor notch must be cut.
 
.303 rifles have had a 7.62x54R reamer run in. The fired cases are a bit odd, because the .303's shoulder is further forward than the 7.62's. The fired cases have a double shoulder.
It is a better practice to set the barrel back enough that the 7.62 reamer cleans out all traces of the .303 chamber.
Any 'smith equipped to barrel work could do it, although finding one with the 7.62 reamer might take quite a search - unless you are prepared to pay for the reamer. It is also pointless to work on a barrel unless the bore is good enough to justify the expense.
A reamer would be about $150, the setting back and rechambering probably another $150 -$200. Have to shoot a lot of surplus ball ammo to offset the cost.
 
There is a delicate step of getting the bolt face, the chamber, the end of the barrel, the extractor, the extractor notch AND the front sight base to all line up perfectly. The big shoulder on a No.4 has room for some very thin "breeching" washers to fill the gap.

Think about how Savage gets around the shoulder alignment issues. They use a big external nut. If you are going to cut new threads, why not run the lathe forward another inch or so? Then make an internally threaded locknut that cinches the barrel to the receiver.
