What I'm saying is that if you have a rifle with say a rough bore, fat chamber, and long throat you will have to add more powder to achieve a given velocity than you will compared to a rifle with a tight chamber, smooth bore and tight throat.
What a lot of people miss is that their rifle with a rough bore, fat chamber and long throat probably isn't going to be able to acheive the same velocities within pressure limits as the better barrel. Just because you load to the same velocity doesn't mean you are doing so at the same pressure.....................DJ
