I have switched from the 250's (Speer and Nosler) to the 225 gr TSX in my Whelen's. With 60 gr of RL 15 it goes right at 2700 fps in my old tang Ruger and worked wonderfully on elk and moose in 2008. With the 250's I used 59 gr with the Speer and 58 gr with the Nosler with both going a hair over 2500 fps.
