What is the speed of the fastest air rifle 177 cal pellet gun in feet per second?
You are saying both "Pellet Gun" and "Air Rifle in the same
question." If it was a rifle it would most likely fall to the "AIR
FORCE CONDOR" at over 1400 FPS, using a .177 barrel. (It has 12
different barrels that fit the rifle)
Pellet guns are not as powerful as rifles. The EVANIX HUNTING
MASTER fires a .22 cal pellet at 1000 FPS. The Fastest .177 air
pistol that I know of is the Crosman 1720T Target pistol that is
rated at 750 FPS. By the time I answer this there may be one
faster
Don't confuse speed with accuracy. Olympic class air pistols
like the "Feinwerkbau P44 Match pistol" only fires at 508 FPS but
is dead accurate and only cost $1,696 dollars.
