Congrats on your raffle win. (I know how it feels; having won two, 3rd Gen SAAs ,and a Benelli SBE II DU Limited years ago). Can't beat "for free!"

In .300 Win Bag? - freakin' awesome! I still remember the first time I ever put a .300 Win Mag to my shoulder and touched it off - big recoil - gotta love it. You will become one with that gun.

Optics? I like Vortex Scopes. Lower price point but reasonable quality. MHO.

Enjoy it in good health.
