Welcome to deer hunting. I think will will like your WSM. I know I love mine. I have a Browning A-Bolt .270 WSM and am shooting Win. ballistic silvertip 130 gr. bullets. I would suggest you go with the 130 grain in whatever brand you decide to use. Ammo may be expensive, but if you shoot straight, you won't need a whole lot. Go ahead and buy about two or three boxes before it goes even higher. I bought three boxes. That will last me a long time.
