If I want to sqeeze a little more speed out of a case (300 RUM) do I need a faster burning powder or a slower one. It has a 26 inch barrel. I'm currently using RL 25.
Another question I have been wondering about. Why is it that a larger caliber bullet in the same case will go faster when using the same weight. 270 vs 30-06 vs 338-06. Is it because of the larger case capacity caused by the larger diameter of the neck? Why should I buy a 270 when a 30-06 will shoot a 130 or 150 grain bullet faster?
