I've considered that same question. Some say it'll go over 2400fps with 225 cup-n-core slugs. May be good for dark timber elk inside 75yds.
Should be about 200yds behind the 338WM.
I've had good results with factory loads with the 185TSX bullet, have some 225 cheapos on hand to play with so may find out how the comparo works out.
