Hi MooseHunter...With the 300 Win Mag I would probably shoot 220's or even the 200's.Reason being,I don't think the Win Mag has the powder capacity to make use of such a BIG bullet...A 200gr MK at around 2850 to 2900fps would be very flat shooting hard hitting round.And yes the 9twist should work very well for you....Buy yourself some 200gr Mk.I think with that sized case you will be very happy.Just my 2 cent's.....And welcome to LRH...R-WEST told me you were coming.....
