With a muzzle velocity
of 1025 m/s and a precision of under 1 MOA, the round is essentially intended for use by marksmen.
Note that even with a conservative estimate for the muzzle velocity
of the 6mm Optimum cartridge, computed data for 1200-meter velocity, flight time, wind deflection, and trajectory height are greatly superior to both 5.
4 grains of #2400, however the muzzle velocity
dropped to 1,232 fps.
2--considerable controversy surrounds this cartridge because, while everyone agrees that it used a 345-grain lead bullet- and 60-grain charge of blackpowder for a muzzle velocity
of 1476 fps, some sources state the case was 51mm in length, while others insist it was 1.
While shooting the 20-gauge rounds over the speed screens, the muzzle velocity
was much the same as in 28-gauge.
60 Length [mm]: 943 Barrel length [mm]: 415 Rate of fire [rds/min]: 850 to 900 Muzzle velocity
[m/s]: AK-107:900 Max effective range [m]: 400
This loading carries a graphite-coated RN bullet and has a factory-rated muzzle velocity
of 1,085 fps.
Given the muzzle velocity
and a G1 ballistic coefficient (BC) of .
5 grains of Red Dot, the muzzle velocity
is 950 to 1,100 fps, depending upon ban-el length and gives excellent accuracy.

294) and low muzzle velocity
of this bullet become an issue when drop, wind drift, and retained energy are important I can think of nothing better for hunting black bear over bait, where shots are close and imparting immense shock is important, but for hunting open country, I'd choose a lighter, more aerodynamic projectile.
Its 173-grain round-nosed FMJ bullet had a muzzle velocity
of approximately 2300 fps.
