[QUOTE="25WSM, post: 1916611, member: 38048"] I can't really answer the ops question with any certainly because I can't think of to many cartridges that have the exact volume of each other with a big change in shape. I do know for certain that a 308 is almost as fast as a 30-06 with way less powder and a 30br is almost as fast as a 308 with way less powder. So it seems that for each bore size there is a point where velocity is maximized with x amount of powder and to gain more velocity you need to add more powder disproportionately. But that's not going to stop me from using all that extra powder in my 257wby to get that 200fps gain over a 25-06. Shep [/QUOTE]
