Properly profiled bullets with a ballistic co-efficiency below .4, can be driven a speeds in excess of 3000 ft per sec, in a 1/10 twist, and still be acurate at well over 1200 yards, even after they've gone sub sonic

I dont really understand how a much softer lead pellet would strip the rifling from the barrel , most shooters of air weapons find a 800–900 ft/s (240–270 m/s) range offers an ideal balance between power and pellet stability. The 1250ft/s stated is an upper limit where really is accuracy is greatly depleted so it is not practical.
