I was just wondering if anyone with a reloading book could give me some info. I was just wanting to know what the numbers are for a .257 Weatherby Mag. (117/120 gr bullet) and a .300 Weatherby Mag. (165 gr.) using the same powder and the same amount of powder. My father-in-law and I were just having a dicussion but his reloading books are at his house, and some hard numbers would be helpful. Thanks
