some numbers...

Thanks Tom, !

Nosler's site shows

From a 14" pistol barrel
120 grain bullet, 2500 fps
140 grain bullet, 2400 fps

From a 26" rifle barrel
120 grain bullet 3000fps
140 grain bullet 2800 fps

My guess would be about 100 fps faster firing from a 16 1/2 barrel than a 14.

Using Hornady Ballistic Calculator

120 grain Muzzle 2600 fps 1801ft-lb at 400 yards 1828 fps and 890 ft-lbs
140 grain Muzzle 2500 fps 1943ft-lb at 400 yard 1807 fps and 1015 ft-lb


So it would be fair to say that a 16 1/2 barreled 7-08 shooting a 140 grain bullet would be an ethical 400 yards deer rifle?
