That's not that terribly overbore of a round... that said, it should work fine; I am using wc872 in my 270win with one milder loading using a 130 and it does decently. I'd work up from about a 90% fill to rather compressed. With the 270 I am running 69.5 gr of 872 and the 130; it's about as much as I can get in the case with bullets seated touching the rifling to help push pressures up...
