I've never subscribed to the theory you have to go to a faster powder with shorter barrels. I agree that an accurate powder is an accurate powder, no matter the barrel length
Case in point.....
I used to shoot a 6.5x284 in 1K BR, and averaged 3075 in several 30" barrels with 142 SMK's using H-4831-SC.
We decided to have a 1K pistol class, so I had a 18" Broughton fitted and chambered in 6.5x284 to my X-P-100. After load work in that barrel, the accuracy charge weight ended up the same as I had used for previous 30" barrels. I was running the 142's at 2740, which averaged 28 feet per second per inch loss over the 30's.
