Why is 7N6 ammo banned?
On April 7, 2014, the ATF reclassified imported 7N6 5.45×39 ammunition as “armor piercing” and banned its importation through a special advisory memo after ATF found an extremely rare and obscure Polish-made pistol that could supposedly shoot the 7N6 cartridge. Only 200 of these pistols were ever made.
Is higher muzzle velocity better?
Generally speaking, a higher muzzle velocity correlates to a flatter trajectory, meaning there is less bullet drop over a given distance when the velocity of a projectile is increased.
What ammo does Russian army use?
It was introduced into service in 1974 by the Soviet Union for use with the new AK-74. The 5.45×39mm gradually supplemented, then largely replaced the 7.62×39mm cartridge in Soviet and Warsaw Pact service as the primary military service rifle cartridge.
Is 7N6 armor piercing?
Accordingly, the ammunition is “armor piercing” under the section 921(a)(17)(B)(i) and is therefore not importable. ATF’s determination applies only to the Russian-made 7N6 ammunition analyzed, not to all 5.45×39 ammunition.
Is 7N6 ammo illegal?
On Wednesday, a federal judge in Seattle ruled against P.W. Arms in their challenge of the ATF’s 2014 ban on imports of Russia’s 7N6 5.45x39mm ammunition. According to their determination, and now the federal judge’s ruling, the bullet’s core is constructed entirely of steel. …
Does more gunpowder mean more velocity?
You will get the highest performance from the most progressive propellant. It will produce greater amounts of gas for a time as the projectile moves faster down the bore, keeping higher pressure on the projectile and producing higher velocity.
How many fps does a .45 shoot?
The standard-issue, military . 45 ACP cartridge contains a 230-grain bullet that travels at approximately 830 feet per second (253 m/s) when fired from the government-issue M1911A1 pistol, and approximately 950 feet per second (290 m/s) fired from the Thompson M1A1 submachine gun.
Is 7N6 illegal?
When was 7N6 banned?
On April 7, 2014, the ATF reclassified imported 7N6 5.45×39 ammunition as “armor piercing” and banned its importation through a special advisory memo after ATF found an extremely rare and obscure Polish-made pistol that could supposedly shoot the 7N6 cartridge. Only 200 of these pistols were ever made.
What is the muzzle velocity of a 7N24 round?
The 7N24 round is loaded with a 4.15 g (64.0 gr) projectile containing a 1.8 g (27.8 gr) penetrator which is fired with a muzzle velocity of 840 m/s (2,756 ft/s) yielding 1,464 J (1,080 ft⋅lbf) muzzle energy.
What is the ballistic coefficient of a 7N6?
The US Army’s Ballistic Research Laboratory measured a ballistic coefficient (G7 BC) of 0.168 and form factor (G7 i) of 0.929 for the 7N6 (M) projectile, which indicates good aerodynamic efficiency and external ballistic performance for the bullet diameter. The rounds are loaded to produce a maximal pressure of 290.00 MPa (42,061 psi).
What’s the muzzle velocity of a M4 carbine?
From the data, the M4 Carbine with its 14.5″ barrel and 2,920 ft/s muzzle velocity meets our velocity threshold at 125 meters, while the M16A2 with its 20″ barrel and 3,150 ft/s muzzle velocity meets the threshold at 190 meters.
What kind of metal is a 7N39 bullet made of?
The 7N39 armor-piercing cartridge, introduced in 2013, has a penetrator made of a tungsten carbide (92%) and cobalt (8%) alloy. The round is loaded with a 4.1 g (63.3 gr) bullet containing a 1.9 g (29.3 gr) penetrator which is fired at a muzzle velocity of 850 m/s (2,789 ft/s) yielding 1,481 J (1,092 ft⋅lbf) muzzle energy.
