American Rifleman -Sniping in Afghanistan

The December issue of American Rifleman has a nice article on rifles and ammunition currently being used in Afghanistan for sniping. They mention the M118LR load for the 7.62x51mm and a new load developed called the Mk 316MOD O. This is also a 175 grain load with muzzle flash reducing additive being produced by Federal. Is there any other information out there on this new load?

There is a long discussion on that subject on Snipers Hide. Bottom line claim the powder used is 4064

The article states it "incorporates a similar ( as for the new .300 win mag load) temperature-stabilized propellant." The new Win Mag load is Black Hills loaded 220-gr Sierra MatchKing at 2850 fps which duplicates the approximate energy and accuracy of a 250 gr .338 Lapua Mag load out to 1500 yards. That seems pretty impressive to me.

The powder spelled out for the 300 WM is H1000 and that was the contract ATK. Maybe they changed to BH now.

I have to believe what they say about the 300 win mag, but the math doesn't add up for me. Unless the velocity is bumped way up to catch up to the .338. The life of the barrel would be pretty short indeed.

Talking

When Uncle Sugar is picking up the tab on ammo and barrels does it matter?

I guess you're right. The rifle and ammo would obviously be a lighter package. That would also match up to the fact that Remington Arms is refurbishing the M24 system to the XM2010 (.300 Win Mag) at their Ilion Plant which is less than an hour from the end of my driveway. Incidentally OSHA just levied $170,000 in fines on Remington at their plant this past week for what I thought were pretty minor infractions.

Checked out the thread a few weeks ago and tried out the 41.7g IMR4064 with the 175 Sierra. Accuracy is very good but velocity is around 2500fps.

Wow, that was quite an impressive thread. Lots of detective work going on there.
