Many of Ozark deer have fell to my dads 303 since 1958. Its the only Rifle he has ever owned. He will be 70 this month, and doesen't even use a scope, although he admits he needs one. I have seen some pretty good shots made by him. He claimed to kick dirt right behind a coyote at a measured 600 yards once. His is a mark 4. You can get stocks, scope mounts and other accesories for them. Have your head space checked, or at least make sure your bolt serial # matches your rifle.
