If you can't - why? That's the issue I have with my .308 - 20" barrel which is fairly standard for a .308 yet seems to be almost 300fps slow whatever I feed it.

Greetings @No.3,
I would be interested to know what velocities you are getting in your .308. I did some comparative chronographing with 5 different powders and 3 different projectile weights in my 20 inch .308 and found the Hodgdons data was mostly pretty accurate once barrel length had been factored in.
