Entwicklungen und News, ...rund um die Infanterie Einstellungen

[Praetorian]

Da es bei den Infanteristen bisher keinen Sammelthread für News gab, und sich diese in den anderen Foren ganz gut bewährt haben, bin ich mal so vermessen und mache einen auf.

Zum Einstieg:
Die Norweger testen derzeit drei Kandidaten als potentielle Nachfolger des AG3 - SIG SG551 SB, C8 IUR und Heckler&Koch G36 KV3:

Choosing the right rifle
The Norwegian Defence’s Logistics Organisation is now testing the candidates for the Armed Forces new choice of attack rifle.
The new rifle will be replacing the traditional AG-3, and representatives from all the branches of the Armed Forces are testing the different candidates.
The three candidates are the C8IUR from Canada, the G 36 KV3 from Germany and the SG 551SB from Switzerland.

SSK 6.5 MPC: Best Assault Rifle Cartridge for 21st Century Warfare?

Small arms designer/developer J.D. Jones of SSK Industries has developed what may just prove to be a superior solution to the 6.8x43mm SPC (a.k.a. 6.8 SPC) and/or 6.5 Grendel (6.5x39mm) cartidges as a replacement for the 5.56x45mm NATO cartridge for U.S. military general infantry and Special Operations (USSOCOM) use. Mr. Jones is calling it the 6.5mm Multi-Purpose Cartridge (6.5 MPC), and on paper, it looks pretty good.
The 6.5 MPC (6.5x45mm) utilizes the...


standard 5.56x45mm NATO/.223 Rem. case. However, to maximize powder capacity (and thus projectile velocity and ballistic/terminal performance), Mr. Jones pushed the case shoulder back a tad and increased the size of the case neck so it would accept a 6.5mm bullet. The result? A 95-grain "SSK Solid" bullet travelling at a muzzle velocity (MV) of approx. 2600 fps out of a 12-inch (12") barrel and approx. 2800 fps out of a 20-inch (20") barrel. So, were' guessing around 2700 fps out of a 16-inch (16") barrel (unconfirmed/unverified). Pretty respectable. Muzzle velocities for the 110-grain Sierra HP version of the 6.5 SPC are 2480 fps (12") and 2731 fps (20"). MVs for the 120-grain "SMK" round are 2220 fps (12") and 2400 fps (20"). 120-grains is the upper limit of bullet weight for this cartridge. Anything above that affords limited ballistic returns. Impact energy (terminal energy) is reportedly 30-50% greater for the 6.5 MPC over the 5.56mm NATO, depending on bullet weights and types, while the weapon remains highly controlloble on full-auto.
The 6.5 MPC page at the SSK Industries website mentions that they've fired a 107-grain SMK round at 2400 fps out of a weapon with a 12"-barreled CQBR-type upper receiver and that effective engagement range is 300+ yards. With longer barrels, the distance is increased.
So, why the 6.5 MPC instead of the 6.8 SPC? Ease and cost of conversion (weapons conversion), ammo capacity, and ammo weight (ammo carry capacity at a given load weight). The 6.5 MPC utilizes standard AR-15/M16/M4/M4A1 magazines and bolts, and will function in both the SOPMOD M4/M4A1 Carbine and belt-fed FN M249 SAW/LMG, provided you switch out the barrel(s). No further modification is reportedly necessary. Mag capacity for the 6.5mm MPC is 30 rounds (although you might still want to down-load it to 28, as many do with 5.56mm ammo for reliability purposes). The 6.8mm SPC doesn't stack properly in standard 5.56mm M4/M4A1 mags, and the magazines that have been developed for it limit ammo capacity to 25 rounds, as opposed to 30 rounds, so the 6.8 SPC mags will fit inside current military mag carry pouches. You can also use 5.56 NATO stripper clips to load 6.5 MPC rounds into the mag. At present, there are no 6.8 SPC stripper clips.
6.5 MPC ammo will reportedly feed as reliably as 5.56x45mm NATO ball ammo can utilize standard M27 links (belt links) with no modification, so it will feed reportedly feed reliably through the M249 SAW. You only have to switch the barrel to 6.5mm caliber. Not so with the 6.8 SPC, which would require modification to the M27 link.
The 6.8 SPC cartridge weighs approx. 40% more than the 5.56mm NATO cartridge. That, combined with the fact that 6.8 SPC mags are made of steel instead of aluminum (making the magazine roughly twice as heavy), means that the infantry warfighter or Spec-Operator will be able to carry less rounds of 6.8 SPC vs. 6.5 MPC or 5.56 NATO.
Reported ammo carry capacity breakdown for the various cartridges at the same carry weight (specific weight unkown, and unconfirmed/unverified):
5.56 NATO: 10 x 30-round mags = 300 rounds
6.5 MPC: 9 x 30-round mags = 270 rounds
6.8 SPC: 7 x 25-round mags = 175 rounds

DefenseReview recommends that you read Stan Crist's article on the 6.5mm Multi-Purpose Cartridge in the #44 issue of Special Weapons for Military & Police (SWMP) magazine. That issue has a photo of a U.S. Ordnance M60E4/MK43 Mod1 Commando "light machine gun series" GPMG (7.62x51mm) on the cover, and the article is titled "SSK 6.5mm MPC: Multi-Purpose Cartridge delivers bet-your-life performance." While SSK Industries Website indicates that they developed the 6.5 MPC round at the behest of one Brian Hormberg (USMC), it should perhaps be noted that Stanley Crist mentions in his article that he wrote about his own idea for a 6.5mm assault rifle cartidge in the #36 Issue of Special Weapons for Military and Police. Mr. Crist called his cartridge the 6.5mm Standard Combat Cartridge (6.5 SCC).

Bottom line, if the 6.5 MPC proves reliable in the AR-15/M16 and SOPMOD M4/M4A1 platforms, is combat accurate out to realistic assault rifle engagement distances, and the AR-type upper receivers and barrels hold up to full-auto fire at high round count, then it may just be the ticket for the 5.56's replacement (and thus a better answer than the 6.8 SPC or 6.5 Grendel) for infantry assault rifles and carbines. Time, money, and politics will tell.
If you'd like more info in the 6.5MPC cartridge and weapon conversions (i.e. upper receivers) that are available for it, Defense Review suggests that you contact SSK Industries.

Es geht um eine neue Infanteriepatrone, die SSK 6.5 MPC (6,5x45mm), die eine am Hülsenhals geweitete 5,56er Patronenhülse benutzt und in Konkurrenz zur 6.8 SPC und 6.5 Grendel steht.
Das Patronengweicht fällt relativ gering aus, 270 Patronen wiegen soviel wie 300 .223er.
Außerdem lassen sich M4/M16-Magazine sowie Verschlüsse weiterbenutzen.[/left]
