.284 Shehane Velocity drop at 100 Yards

[Killick]

Trying to calculate approx. velocity drop in fps for a 180gr bullet at 100 yards. Forgot the V3 Mag speed but have the Shot Marker velocities. F Class 284 Shehane, from 2670 to 2718fps. 55.6 to 57.2gr N555 These are FF loads.

Mine at 2848 at muzzle is 2720 at 100 yards according to ballistics data sheet from Berger with all my info. That's 700 feet elevation at 60 degrees using 180. You can go on Berger website and use the ballistic calculator to get that info.

Thanks Bill, you’re a real peach.
