I'm wanting a Tikka T3 Lite in either 7mm Rem. Mag or 300 Win. Mag for some long range deer hunting on a lease I have . Shots probably won't be over 500 or 600 yards . This is the rifle I am set on but I just can't decide on which caliber I want . I just gave my old Remington 7Mag to my son so I am leaning toward the 300 just because I have never owned one . Any suggestions on factory ammo from Tikka owners would be appreciated . Experimenting can get expensive ! Thanks
