FWIW:

Dogzapper used a 25-06AI to zap an antelope at over 400 yards.

The IMPACT velocity was likely less than 2900 FPS.

I believe that the guys at Nosler were referring to IMPACT velocity (not MUZZLE velocity) when statting that the B-Tip was not designed to work above 2900 FPS.

Hope this helps with the anlaysis,
