I shoot a Savage 300 Winchester short mag and I love that gun. I've hit good paper (and prairie dogs) at longer distances than I expected. Mine has the accutrigger as well and man I LOVE that trigger, but that caliber lets you know (for a few days) when you don't have it pulled tight to the shoulder. Before that I shot a Ruger 308 Win that I think I like more than the 300 WSM. It's controllable on the fly, accurate, and its range is quite impressive.
Scopes I've used include Burris. That's it. It's what my Dad bought and I'm not complaining.
what I really like though is the ballistic crosshairs. Easy to aim and judge range quickly.
