I'd guess 875. There is no definite answer because every gun is different. If all the bore sizes where the same, and every powerplant shot every pellet at the same velocity... you get the picture?

760 tops. i have a chrony.
my storm throws 7.9 @ 875
and 9.8 rockets @ 770ish.

740 would be more real.

no 1000fps rated .177 will hit 950/7.9.
