•
Status of Previous Recommendations. This is the first annual
report for this program.
•
FY13 Recommendation.
1.
The Army should continue to improve the complex
computer models it uses to model small caliber ammunition
performance.
Activity
•
The Army successfully completed live fire testing of the
Mk248 Mod 0 in March 2013. Testing was conducted in
accordance with the DOT&E-approved live fire strategy and
test plans.
•
The Army used gelatin targets to obtain data as inputs for
complex computer modeling of Mk248 Mod 0 performance.
Testing also included shots against light material barriers and
other targets to determine the projectile’s ability to perforate
the target.
•
DOT&E published a classified lethality report for the Mk248
Mod 0 in June 2013.
Assessment
•
The Mk248 Mod 0 demonstrated adequate performance and
lethality when fired from the M2010 ESR.

Executive summary
•
Snipers will use the Mk248 Mod 0 cartridge in conjunction
with the M2010 Enhanced Sniper Rifle (ESR) to defeat
specified targets at greater ranges and with improved accuracy
compared to current sniper systems.
•
DOT&E assessed the Mk248 Mod 0 as lethal.system
•
Army snipers use the Mk248 Mod 0 cartridge in conjunction
with the M2010 ESR to engage enemy targets at extended
ranges.
•
During Operation Enduring Freedom, the Army identified the
need for an upgraded sniper rifle capable of firing at longer
ranges and with improved accuracy than currently fielded
sniper weapons. The Army determined the M2010 ESR, a
reconfigured M24 Sniper Weapon System modified to fire a
.300 caliber Winchester Magnum cartridge, was the preferred
solution.

ESR will engage designated enemy targets in accordance with
applicable tactics, techniques, and procedures.
Mk248 Mod 0 Sniper Round

Hell, I could've told them .300 win mag will reach out "and touch someone" at extended ranges and punch holes in s@&t too, for half the price of course..;)

In 1956 the US Army Marksmanship Unit (AMU) was established and much testing was done over the years. The 300 Ackley Mag was used and both Winchester and Remington provided the cases (headstamped WCC 60 and REM-UMC 300) photos show some examplesAttachment 49762

It's not like the idea of using the .300WM is new for the M24 platform. That's why it was procured as a long action in the first place. Barrel, magazine and bolt swap. But without the hassle of allocating funds for a whole new weapon.

The Stryker BDE in AK was just issued the M2010's. I will try to post some pictures of them latter. It is a very impressive weapon.

So the system that was current (NATO round) is being phased out, this will mean the opposition is getting the drift and keeping out of a reliable hit range of this cartridge I mean how scary would it be to not even hear the report of the rifle and your comrade in arms h**d explodes so stay way way away from known hot spots.
In all seriousness what does this mean for the current longer ranged weapons systems like the Barrett line 50, 416 and the 375 Chey Tac are these now role specific as the 300 Win Mag offers a more portable system for the operator with the added benefits of increases accuracy and longer range.

I have just seen footage from a developer that after years of research and trials a 50 cal steerable round has been developed so as long as the operator keeps you in the cross hairs the round will follow you and pin you to the ground permanently bit like a Milan and a Tank scenario
The round is a sabot type with the miniature processor contained in the progie and fins, this is quite a leap as when you think of the rather violent launch, the rotational forces applied to the unit it is quite amazing how fast the unit inputs data and alters the flight path whilst keeping it on track to the intended target.

All of those exotic rounds and weapons are sexy but expensive, heavy, and heavy recoiling. They are good for SOCOM or some mission specific cases, but no good for your average infantry sniper. Her needs something portable, accurate and reliable. He gets issued ammo. He does not set at home and reload it, nor is he necessarily a gun nut. A good buddy of mine was a sniper in VN. He knew very little about ballistics. I tried to talk ballistics with him, and he did not know enough to make it interesting. He was a great shot, and very patient.

Here are some pictures of the M2010 sniper system. It replaced the M240. The M2010 is a Remington long action with a SS 5 grove barrel, in 300 Win Mag. The Scope ia a Leupold with a hours reticle. The soldiers are from the 172nd Stryker BDE in AK.

Why is Remington tarting up ALL their new firearms! More subtle markings would suffice..:banghead:

What you gotta know is that the sniper is going to grab 2 or 3 rattle cans of paint and cammo that thing up as his first order of business. That big black scoped rifle is what we call a target indecator.

Old Soldier means the M24 SWS not M240 which is a GPMG. AMU shooters have been winning long range competitions for years with M24 rifles converted to .300 WM.
