Yes - I think you might attain 2,000fps with a 250gr. form the carbine's 20" bl., considering the 220's will run well over 2,200fps, 2,000 isn't out of order. Be prepared for quite heavily compressed loading. AA1680 might be a better bet, although it seems to be on the fast side, I've run, but not chronographed loads that are supposed to run 2,400fps - bl. length not known. theywere fire and much snortier than typical 38.0gr. Re#7 loads, using the 220gr.
The factory 250gr. PP Winchester was a good bullet. I'm not familiar with any other flat point in that weight and calibre.
