Home Forums Hunting & Shooting Ask The Gunwriters Ask John Barsness Questions About "The .300 Weatherby"

John, I've always been puzzled by the frequently published claims - not alluding to your writings - that the 300 Wby can drive bullets of equal weight and type to MVs equal to or higher than the 300RUM. Given the physics of the 2 cases, the same bullets at equal chamber pressures and barrel lengths would seem to dictate advantage RUM. We might argue lack of practical differences in game performance or trajectory, but IMO not absolute equality in measured performance. I've not tested this hypothesis as I don't shoot the Wby. Is this type of thinking off track?
