Wait, is that “pistol” shooting 30.06?
No, it fires .30 caliber carbine rounds.
Bullet mass/type: 110 gr (7 g) FMJ
Velocity: 606.5 m/s (1,990 ft/s)
Energy: 1,311 J (967 ft⋅lbf)
Test barrel length: 18 inches
Source: Winchester
Nearly 2,000fps from a 18in barrel with 110gr bullets.
It’s no ought six, but effective out to 100yds.
With an expanding bullet it would be a wrecker.
