Anyone know much about this particular military mauser?

Had an interesting rifle follow me home from the pawn shop today. It's a 1909 Argentina military mauser in 30-06. It has the original stepped military barrel and a mil grade stock although it's been sporterized. It also had a scope mounted to the receiver and a sling. No pitting anywhere and the rifling in the barrel looks brand new. As a mil surplus rifle I realize this probably doesn't have much collector value since it's been tinkered with and sporterized. I bought it mainly for deer hunting and target shooting. I only paid $365.00 for it. Did I make good choice?
 
If the chamber has been reamed to accept 30-06 cartridges I wouldn't worry about collector value but I would be concerned that if it is the original barrel that used .311 or .312 bullets that a .308 bullet for the 30-06 is not going to be too accurate.
 
Steel Horse, I thought 30-06 was the original chambering for the argentine 1909 mauser. Are you sure these 1909 mauser mil spec 30 cal barrels had .311-.312 bores on them? I do know that the Russian Mosin nagant 7.62x54 rifles came with .311-312 cal barrels.

If I'm remembering right, the 1909 Argentine was chambered 7.35x50-something. So, if it's the original barrel, it was chamber-reamed to .30-06 length, but as was mentioned, the bore is to big to be accurate with the .308 diameter bullets. That said, you are looking at plenty of options.
 
I guess one way of seeing if this has a .311-.312 cal barrel is to drop a .308 cal bullet in the chamber. If it ends up sliding down the barrel under it's own weight that question will be answered.
 
I have shot a lot of 308s from the argentines both 1891s and 09s they can shoot pretty well. A flat base bullet seams to be best. Mine pictured above is now a 7x57Ackley improved. Build by John van Patten he was the shop Forman for Ackley for some years. This is the last rifle before he died, so it's special to me.
 
The 1909 pattern Argentine Mauser was chambered in 7.65x53 with a bullet diameter of .313”. So, if the original barrel, .308 bullets will not be a good fit. Also, the CIP max pressure is 56,500 psi, so lower than 30-06, but the loose bore will alleviate pressure in any event. Slug the barrel.
 
The 1909 Argentine was chambered for the 7.65 Argentine ( 7.65x53 Mauser) which uses a .311 diameter bullet. A few gunsmiths simply ran a 30-06 reamer into the original barrel to create a "31-06" or 7.65x63mm wildcat.
 
I wish I had known this information about the possible .311 bore size variation before I had bought this rifle. I'm going to take it to a gunsmith and have the bore size checked. If it turns out to be a mismatched barrel I guess I'll get a new barrel blank and have it rebarrelled to the 35 whelen. I am hoping it's going to have the proper .308 cal barrel for 30-06 though.
 
Even if it is the larger bore size it is not the end of the world. Bullets are available that will fit. A different expander may be needed ,but , then again maybe not. The big thing will be if the chamber is correct for using 30/06 dies and or factory ammo. You won't know for sure without a chamber cast.
 
I shot a 1909 rechambered to 3006-.308 and it was a decent deer rifle with the .312-.313 original barrel, but with the correct diameter bullets it shot much better. TROY, I have a rifle built by john van patten on a steyr 98 mauser action in 35 whelen, a nice rifle indeed.

I saw an Interarms Mark X marked 30-06 at the LGS. Had a stepped barrel, I assume original Really nice wood

I have zero idea the origin of the action, other than it appears to be Mauser. Would it be .311 or were there actual 30-06’s?

I have a 7 mag so I have zero use for it, just wondering
 
I have pretty much the same rifle that you describe. It's a 1909 originally chambered in 7.65x53 that had the chamber reamed out with a 30-06 reamer. There are tons of them out in the wild. The bore on mine slugs at 0.312" and doesn't shoot most 30-06 very well but I did find a box of 180 grain round-nose rounds that actually shoot decently in it. I got about 3" groups at 100 yards with those while the standard 150 gr SP were in the 8"-group range. Mine is destined to become a 6mm Remington, hopefully sometime next year. It's far and away the smoothest Mauser action that I've every handled.

There not very common how did your find yours.
 
believe it or not, at a local flea market. a man had it in a case and I ask to see it and I bought it as I have two other 35 whelens, a ruger #1 and a Remington 7600 pump.
 
From a reloading standpoint, totally not an issue. There are plenty of component bullets available (usually listed as 303, 7.7 jap, or 7.62 russian) for basically same cost as the standard .308 bullets. You won't need anything different than a regular 30-06 die set if the bullet has just the slightest heel taper. Negligible if any changes to load data.

The barrel has the same markings as mine so it's a late gun. His early stuff just had VP on the barrel. How's it shoot.
