[QUOTE="TRexF16, post: 2213555, member: 108912"] Hey, you did better than Nosler. Their top load with the 250 Partition in the 340Wby only gets 50 FPS more than their top load in the 338WM. Their data show about a 22% increase in powder capacity for the Bee, so we'd expect more like 150 FPS increase (5.4% velocity increase - since velocity potential increases at about 25% of capacity increase) if both were loaded to the same pressure and other variables constant. But, the 338WM is a SAAMI 64K round, while the 340 WBY is SAAMI 63K. This could explain some of the "underachievement." But they shot the Bee in a 26" Lilja and the WM in a 24" Wiseman, which should offset that - go figure... Cheers, Rex [/QUOTE]
