Good choice!. My 300 WSM is a 1 in 10 twist. Mine shoots the 180 grain the best. My buddies is a 1 in a 11 twist and his shoots the 165 grain the best.

Don't worry about ammo, there is plenty available. Online or in the store.

I'd be interested in knowing what your twist is and how long is your barrel?

You are going to be very happy with the short action and the shorter barrel. That gun should be a pleasure to carry for years!

Congrats!!
