Mauser K98 in 6mm remington

The old Weaver K4 scopes with a steel tube are a solid decent quality scope. I think they are referred to as "El Paso" because that is where they were made. The optics are not that great by modern standards, but passable, and they are know to be good reliable no-frills scopes.

If you decide to replace it, or want to trade it for one with a standard reticle, let me know by PM, I have a couple of them, and have had my eye out for one with a German Post reticle.

If it is not marked, you really should do a chamber cast to be sure. The 6mm Remington, (it that is indeed what it is) is a good varmint caliber, that may be why it has a heavy contour barrel.

I am having a hard time making out the Waffenampt number on the right side, is it 135? That would point to Mauser Oberndorf, 1941-1945

The fact it has a 1907 style sling make me think it was owned by a vet.

Nice looking rifle.
 
Determining the twist rate: Use a patch on the cleaning rod that is tight enough that the rod turns when pushed through the barrel.

After starting the patch down the barrel from the muzzle, about four inches in or thereabouts, mark the rod at the muzzle. Pentel pen or just a piece of tape wrapped around.

Make another mark along the length of the rod a little over a foot away from the muzzle.

Push the rod on down the barrel until the index mark makes one full revolution. Mark that spot on the rod, at the muzzle.

The distance between the two marks is the twist rate. One turn in X inches.

+1 to that. But I'd almost be willing to bet money it's a 1:9 twist.
 
[ What short action you talking about?]

The Rem actions in rifles chambered for the 6MM Rem were short actions. I am not 100% sure about the 700s, but I have a Rem 660 and it is a short action.
There would be no problem in a Mauser, or most other rifles, but Rem made them in the same action lengths as the .308 which was a short action.

I have a .243 M70 Pre 64 Fwt and it is not a short action. It permits loading to a longer OAL than the short actions. I can easily get 150 fps greater velocity than in the M660. I realize that the barrel of the M70 is 2 inches longer, but that would not account for the greater velocity.

Sorry it's taken so long to get back to this thread but, as uaual, life happens. I finally got into possession of the Mauser and have since deduced a couple of things: it does appear to have a 1:12 twist rate and unless it was just horribly not sited in prior to my buying it or it simply doesn't like Federal 80gr soft point ammo. Because although it was cold a raining the day I took her to the range I was only able to get one round on paper at 50 yards before the weather turned on me but I could have sworn that there may have been a few keyholes (hopefully just ripped wet target paper though)

Any info on what I can do or recommendations on who would possibly want to take a look at the gun would be appreciated.
 
I would suggest a thorough cleaning of the bore followed by a close inspection (with a magnifier) of the muzzle crown before waste of ammo. Before doing any more shooting, do a bore sighting check also. Set the gun on sandbags or solid rest, pull the bolt, align the bore with the center of the target(or any smallish prominent aiming point), and see where the cross hairs are setting. Twiddle the knobs until the crosshairs align with the bore and shoot from the solid rest to determine point of impact is on the paper.
 
1 in 12 twist for a 6mm bore is slow and going to favor light bullets. It should be fine for varmints but no good for heavier bullets that you may want for using on deer.
When Rem introduced the 6mm it was named 244 Rem and had a slow twist that resulted in slow sales and bad press. They renamed it 6 mm after changing the twist to 1 in 9.
 
Oldscot3 is probably right. If it was done a while back, it may be a .244 barrel. I picked up a take-off barrel a couple years back for almost nothing. It was an old .244 (Same as 6MM except for twist rate) and I ended up using Hornady 100 grain RN bullets so I could use it for deer. Not a tack driver, but it worked OK. The .244 was marketed as a varmit gun when it came out.
 
With a 1-12" twist, its a .244, not a 6mm!;)

They renamed it 6 mm after changing the twist to 1 in 9.

Coming on the market after the .243 Win had its head start, and with several influential gunwriters taking up the 6mm bore size as a good varmint & deer caliber, Remington's decision to make the .244 as a varmint round has always puzzled a lot of us.

Sales never really took off, and once word got around that the .244 wasn't very accurate with deer bullets, sales fell even more. Remington changed the .244 twist to 1-9" after a couple years production, and the rifles do shoot well with this twist and deer bullets (100gr). But, sales stayed in the dumper.

Remington then changed the name of the round to 6mm Remington, and this helped enough that the round has survived.

The other side of the coin is that the stories about the .244 not shooting deer weight bullets accurately are really a partial truth. While its quite true that the slow twist barrels don't usually group the heavy bullets as well as they do the varmint ones, they are almost always "minute of deer" accurate with the deer bullets. It was a matter of perception, and confidence more than actual physical inaccuracy.
