Hello Idaho, and welcome.
I guess first thing comes to mind is given your success with the 7mm, why you didn't pick a rifle in that chambering?
In any case, I'd have probably gone with a plain old 300 Win. Mag., but the 300 WSM should prove ok. I suspect it will be around down the road, but then again if not, it's
always a good excuse to either get into handloading ammo (if your not there by then
anyway), or to buy a new rifle.
BTW, congrats on your first buck!
