My 715 chrono today.
Temp 2C
New ASG gas not warmed.

AA Diablo 290fps.
H&N ftt Green .36 gram between 364 and 379 fps.
This is AGS suggested weight.

All shots single action.
But then Baz suggested double action and with the Greens 419 fps!

By comparison my Umarex Colt Python did just 290fps tho it is only a 4 inch.

Again the 715 performed well on can bashing and I think it is a proper air pistol which will be even better when it's warmer!
