358 Win Mauser? Need help to I.D.

[NyFirefighter357]

I found this rifle in a LGS, I wanted to I.D. it before I bought it but I didn't have time. I went back today & picked it up. I got it for a fair price, the rifling is good & action smooth. Can anyone tell me anything about it from the pics?

You have a nicely sporterized Yugoslavian Mauser. The writing on the side of the receiver with the number 44 basically means "factory # 44" where the rifle was made. I'm a little confused about the 1925 date stamp, as that would mean this was an M24 rifle made by Fabrique Nationale in Belgium and sold to the kingdom of Serbs, Croats, and Slovenes (a precursor to Yugoslavia) after the first world war. But the "factory # 44" marking means that this action was made in Yugoslavia as a Model 1948. Most likely there's a crest of communist Yugoslavia on the receiver ring underneath the scope mount indicating that this was an M48 rifle.
Both the FN and the Yugo M48 are intermediate length actions. This would make them a good choice for sporterizing the actions for cartridges based on the 308 Winchester. The 358 Winchester makes a fine cast bullet cartridge, and is a good choice as a deer rifle out to 200 yards. There is limited collector value to this rifle in it's military form, so contrary to the usual situation with sporterized Mausers, your rifle is probably worth more as a sporting rifle, though it's value is more for it's usefulness than for it's monetary value. I say put a nice sling on it, sight it in, and go hunting.

That is a good caliber for that action.
I built a couple on 24/47 Yugo actions.
I wanted to do one in a 35 Whelen , but the shorter action on that model would have made it hard.
But 20-06 worked really well.

Looks like a decent shorter/conversion. I would return the bore to bright steel, first thing. Foul Out or a bore soak to get all of the old crud out of it. Then prep it for cast shooting. You know it has been shot with jacketed bullets so, de-copper the barrel first, before you shoot cast.

The 20-06 is known as the 5x63mm in Europe....[emoji16][emoji16]

the 20-06 is WAY overbore!!!! [smilie=b:

[LAGS]

Sorry.
The 20-06 was a typo on my part.
It is a 25-06 built on a 24/47 Yugo action with a stock I built from a Walnut Blank.
I have several more of the Yugos and a couple of 257 Roberts barrels.
I build rifles for myself , and haven't needed to build any other ones recently.
I was going to make the 25-06 into a 25-06 Improved.
But the loaded length with the longer heavier Boolits would have problems feeding.
But the 25-06 with the standard loads feeds great and shoots very flat.
The .358 Winchesters that I built , (one with an F34 barrel profile and the other with a F54 profile) both shot great with jacketed or cast Boolits.

Thank you 405grain, I suspected it was a Yugo Mauser. My intention is to shoot cast, mostly pistol bullets killing paper using Unique. I have to get dies & decide if I want to make brass or buy some. I'm doing the same with 336 in 35R but figure it's easier to buy/make the brass for the .358W. We can't hunt deer (or anything else during deer season) with a rifle here but would rarely get a shot over 200yrds anyway. I don't hunt much any more anyway. Funny rule here is we can use a rifle for varmint or predators outside of deer season.
My wife saw a 350 Legend and wanted something along those lines. I figure this will fit the bill as well.

You will be very pleased with your rifle. I had an intermediate action, 1922 Brazilian FN, built into a 358 Win about 30 years ago and it’s a please to hunt with. It’s set up with Williams peep sights and has a 20 inch barrel… very handy.

[frkelly74]

I had a couple of the 24-47 Yugos and they all appeared to be new rifles installed into used stocks. They had very smooth actions and were just ideal candidates for making a sporting rifle.

I take the 1925 as a serial number on the floor plate?

I don't know it doesn't match the serial * on the receiver.

[Silvercreek Farmer]

It'd be interesting to know the twist rate if you get a chance. The Lee 200 shoots well in my 358 and you get 6 at a time.

[1Hawkeye]

Who ever did the work knew what they were doing. Thats a nice looking setup encluding the knife handle type bolt handle. 44 actions are good strong steel so no worries there. A cast 200gr with around 10.0 grs of unique should be a sweet load for it.

[NyFirefighter357]

I will try to clean the gun up & slug the barrel Sunday.

[NyFirefighter357]

Slugged the barrel tonight two times. .358 but the bullet looks like a have some rough area. They were hard to start in the chamber and free bored about 3" before the muzzle.

Interesting markings. I've seen quite a few marked "PREDUZECE 44", but never in Cyrillic or whatever those symbols are.

The Yugo rifles are probably a good field for research if the book hasn't been published already. I've come across a few that are most likely re-stamped German rifles with short K-98 handguards that end at the front of the rear sight, complete with the odd Nazi eagle stamped on the small parts. Hard to say no to free equipment.

[NyFirefighter357]

Turns out the barrel was full of crud near the chamber. I'm still cleaning it but the next 2 slugs came out much nicer. I got 1:13 but I'm guessing it's 1:12 twist.

Glad to hear your barrel is cleaning up better.

[bcp477]

The "1925" number is NOT a serial number or year of production, but rather what was referred to as an "assembly number". In a nutshell, the rifles were fitted with all their parts during initial assembly...final fitting and any bugs worked out...then, the major parts were given the assembly numbers. Then the rifle was disassembled...and the parts sent off for final finishing. The assembly numbers, as you can imagine, were used so that the correct parts could be put back together, to make the finished rifle.

Over the years of use and periodic refurbishing in military service, it was not uncommon for certain parts to be mixed up, hence mis-matching floor plates, etc. All matching numbers are important for collector purposes, but not for function, as long as the bolt assembly and the receiver match ( that is best, as they were fine-tuned together at the factory...but that doesn't mean that a mis-matched bolt/ receiver won't work...only that matching bits will be smoother together).

[bcp477]

Looks a bit like the barrel could benefit from lapping (it appears to be a bit rough). This is a step often omitted in this day and age. Perhaps further cleanup will eliminate the roughness. The REAL test, though, is shooting it. Even if the bore is a bit rough, it may shoot well. Perhaps very well (I have seen that with several rifles). The downside to a rough bore, that still shoots well, is that it may foul much more quickly and be more difficult to clean up. Time and use will tell...

[Uncle Grinch]

Looks like you’re good to go.

12 is a very fast 35 cal twist. Usually they are 14 or 16.

[NyFirefighter357]

I cleaned the fouling with Bore Tech Chameleon which also has a "micro" polish. https://www.boretech.com/products/btck-40002

.358 Winchester specs are: Rifling twist 1-12

Because Winchester "spec'd" it for their barrels does not mean 12" is an optimum twist for cast bullets. A 14 0r 16" twist would be better for top end velocity with accuracy using cast bullet loads.

However, that being said, I wouldn't turn down that rifle because of the 12" twist should you decide to "gift" it to me......:groner:

Merry Christmas to you and yours

I agree Larry, I'll make due with it though. Now to work up some loads.

Learn something everyday. I recently ordered a 35 cal barrel and my choices were 14 or 16 for .358 (16, 18.75 and 20 for .357 groove). Winchester was ahead of the curve on this one!

Your rifle appears to have been stocked with a very popular (when it was sporterized) Bishop stock.

That's nice to know, it also has a Bold trigger #613 as I found when I removed the stock.
