i use the 444 in the tc encore with a 23" MGM heavy factory barrel in a 1 in 20" twist. the 300gr fn gc is really good at putting deer down. the 300gr only goes 1624fps but it is great for 100 yards and under. in the area i hunt, 50-60 yards is a long shot. 30 yards+/- is the average. i have done 2300fps with 265gr jacketed, but my shoulder is not what it used to be.
