[QUOTE="widetrackjack, post: 3005499, member: 120893"] When looking at the difference in velocities between the two of them in a reloading manual you’ll see that most of the time there’s only about 100fps difference. This may be true but it’s been my experience with 6 or 7 different 300 Wby’s that their most accurate loads are often at max or even a few grains over max. I cannot say the same for the 300 Winchesters I’ve played with. They often have to be loaded down to get satisfactory accuracy. So in the real world, there’s probably a 250fps difference between the two of them if accuracy is to be taken into account, which it should. Also, Sierra bullet company used to send out a quarterly bulletin on accurate hand loading. In one edition they discussed loading accurately for “free bored” rifles. Their research showed that seating the bullet way out near the lands was not the best way to achieve accuracy, but on a free bored rifle, to seat the bullet farther down into the case. It’s been my experience that this is 100% true. Weatherby guarantees the accuracy of their rifles, and the ammunition they sell does not have the bullet seated way out of the case. Roy designed long necked cases to aid in bullet alignment so as the bullet left the case it would enter the free bored barrel straight. Maybe Roy Weatherby knew what he was doing after all. He was on to this whole thing well before the “Plus P” bandwagon got started. Just my two cents. [/QUOTE]
