@defencewithac Regular powder, just adding a few more grains of it to raise chamber pressure to 80kpsi vs the previous 55-62kpsi. This is made possible with SIG's new steel base 'hybrid' case first developed for the NGSW program, and now also being used by Federal with PEAK and Shell Shock NAS3
In Seekins video on their new High Pressure barrel tech, we get a sneak PEAK of .338 Norma using Federal PEAK alloy cases. 300gr @ 2950fps, about 250fps over brass. This will likely add 100-200yd of AP range.
The other huge advantage is how much shorter the MFMD is then a normal suppressor ~1" longer then a rifle with just a surefire flash hider. This allows for longer rifle barrels while keeping the rifles overall length compact. (sad bullpup noises)
The Multi-Function Muzzle Device (MFMD) program began in 2022 after special operations users identified a long-standing problem: operators had to choose between sound suppression, flash suppression, or recoil reduction. The goal was to combine all three into a single scalable -
@autisticarab There's probably much better examples but I can't help being reminded of 12.7x55 STs-130 VPS's dual tungsten core AP round, where it has an additional sliding/backing core to push the front during penetration
@vbgamer17 Yes tracking the prices of the ADVAP and now the 6.8, prices have not gone down, and now with the exploding cost of Tungsten this year I expect next years prices will be eye watering.
M1162 .338 Norma tungsten armor piercing is $10 a shot, less then the cost for the 7.62 ADVAP or the 6.8 'SP' load for NGSW. Perhaps a less sophisticated projectile?
@MortarFFE Yes, I suspect this will be a SF only, special mission type load. Assuming $20 estimate was accurate, 5x mags would be $3,000, 7x mags $4,200.
SIG's 5.56 HYP 97gr Tungsten AP projectile shows a novel 'tandem warhead' design, where a front tungsten cylinder is designed to shatter the ceramic, while a follow on pointed penetrator is designed to then punch through this weakened area. May be the key to defeating Level IV.
@vbgamer17 Yes, I suspect the same. Which then suggests the EPR style of tungsten penetrator is quite a bit pricier to build then the regular jacketed variety - poor omen for NGSW and other smaller calibers trying to AP.
I suspect the future is AI drones designed to simply fly down the railroad tracks at 5' high until they strike something or run out of battery. Would be fairly simple level of autonomy, and immune to jamming.
Also included in the release was the ToobTM for The Raped
TsNIITochMash's single-shot 12-gauge, which weighs just under 1.8kg. It's meant as a last resort option against drones
