Yes for the 7mm WSM and 175gr Sierra BT GK .,...excellent.....suggest Reloader 25 powder with heavy bullets.........very good BC. Maybe Norma MRP powder would be cheaper in New Z and a excellent powder.
For the 300 WSM I would draw the line at 200gr for the short case. I prefer the 180 to 185gr bullets and H4350.
I have two Win 70 in each of these cal.........really like the 7mm WSM.
