Carts,
The table I posted is a general representationbased on velocity not caliber, I'm sure there are extremes at both ends of the spectrum. For example cut 2 inches off .308 and a 300 Weatherby Mag. Both have .308 dia. bullets but he 300 WM is going to lose many more Ft./sec. If you want exact #s you would have to look at case capacity/efficiency, bullet weight/ dia., and barrel length.Something to do on a rainy day.
