Another CMP sniper?

[Dan in NY]

probably not, just was curious as to what a 300 win mag 40X would be doing on the CMP auctions?

Long Range Wimbledon Cup rifle for AMU or something. For many years, the 300 win mag has been the US choice for 1000 yard matches. Goes all the way back to Gunny Hathcock's Wimbledon Cup win.

As far as I know the 40x .300 Win mag was never actually issued as a sniper rifle, though the M24 system was designed around the potential for .300 win mag conversion.

I've seen these builds in long-range competition. You load (single round) by removing the bolt, insert the cartridge, put the bolt back in and chamber, shoot.

The Navy uses a .300 Win Magnum bolt action as a sniper rifle. I suspect other branches do also.
When I spent a weekend last February working in the small arms facility at NAVSEA Crane there was a civilian (who resembled Charlie Daniels) working on a rack of them.
I suppose I should add, I saw several of them in the armory of a SPECWAR unit a couple of years ago when my brother was the team's supply chief (not a SEAL) The GM1 who ran it showed me one. I asked him how many shots they put through one and he replied "we box them up and ship them to Crane when the round count hits 1200 So, I asked him about the M14 snipers and he said "same for them" . I commented that as a competitive shooter I expect to get at least 4000 rounds out of a barrel. He said I just do what I'm told, 1200 rounds and back they go for rebarreling.

wouldnt think they would use a single shot for Sniper use.

Looking closer, it seems to have a 3/8" or 1/2" thick recoil lug...I think they leave the factory with .25" lugs...I guess this caliber calls for it...

[chuckindenver]

i noticed that..id say, it was an non Remington part added by the military.
ill post a picture of a 40XB that i own, with a notch cut to clear the .300 mag.
though the rifle is a .726mm.

[chuckindenver]

i have this rifle sold, but i figured id share the pics.. with respect to the future owner ill not post the serial.

That notch on your 40X is not to clear a 300Magnum cartridge. It's to allow stripper clip feeding of a 308 or 7.62 length cartridge.

I'll see if I can find some pics to illustrate that;

Here's a pic to show what the clearances are like for a Rem Short Action ie 40X.


Here's what a 7.62 looks like in comparison to a standard 40X receiver without the clip slot or front relief cut;


It's worth mentioning that all 40X's are going to be short action...even the magnum calibers. The pic above is a 40X solid bottom, single shot in 7mmRemMag. I don't have to remove the bolt to feed cartridges.

I know that the Army Special Forces (Green Berets) used the 300 Win Mag not too many years ago. I think they still do and I believe it's the M24.

The Mk13 is in 300WM.

There are plenty of M24s that are found in 300, I've had several. Usually in a Mac A3 or A5 type. Tackdrivers all around with some big thump.
Check out various threads on the M24 and Mk13 at www.snipershide.com
Big Army just bought a new batch of 300 ammo that is likely to be very good.
If remembering correctly, my M24s would get rebarrelled at 5000, whether it needed it or not! 300 barrels can tend to get burned out after 1000 or 1500 but the new ammo is supposed to extend barrel life.

7mm rem mag 40x

I've got a 40x (single shot) in 7mm rem mag too, you can load single rounds without removing bolt, and eject spent brass normally, but to extract an unfired round, you have to at least release the bolt for the bullet tip to clear the short action ejection port. Bought the rifle with a Redfield 6-18 variable used at Carter's Country in Houston back in 1975 for $150. The rifle shoots great, an honest 1/2 minute gun.

Sounds like all that mumbo jumbo to use the rifle would be a deal breaker for a combat rifle.
More than likely the CMP rifle is a former match gun or the remains of some experiment.
