Matching velocity, bullet, and brass could be done with probably 15 different powders. The individual who posted the load sheet on the first page gave the best info I believe. the are the actual specs. Why beat a dead horse. Also, why not make a better round. They kinda die at 1000. Why not try a 185, 190, 195, 208 with the same velocity and see the longer range potential. I get 2600 with a 208 with no pressure signs and no powder crunching out of a 22" barrel with <.6" groups at 200 yard zero. Sub moa at 1000 and still does good at 1400.
Just a thought.
