The model ASI Paratrooper and the Gamo Gamatic 85 are the same rifle. Just different name. The muzzle velocity is rated at 560 FPS.
muzzle velocity is the velocity of bullet and recoil velocity is the velocity of gun.
the muzzle velocity on the 40gn vmax is 2200fps
it is the instantaneous velocity as a projectile leaves the barrel
It depends entirely on the muzzle velocity of the weapon you are using. The higher the muzzle velocity the farther the projectile will travel.
no, if your gun is below the legal muzzle velocity which is 12 ft/p/lb [12 feet per pound of force]
@ 1000 fps
Muzzle velocity of the SS-109 cartridge is about 3100 feet per second.
