I have a Ruger Gunsite Scout Rifle in 308 Win. Mine is in stainless and laminate with an 18" plus some 1/10s barrel length. For my purposes this gun has it all for a knock-a-bout all purpose rifle. You could probably have it bored to 338 Fed. if you are not satisfied with 308 Win. It is built like a tank. Extremely accurate and shoots most factory ammo very well. Has option for scout scope or standard scope mounting. Also, comes with a very good ghost ring in case your scope goes south. This gun is built like a tank, has spacers for an adjustable stock. This one will do what you want off the shelf.

There was no greater freedom than when I would leave Holiday Park Fish Camp heading my airboat west toward the Big Cypress. Fuel for 4 days, a good machete, an ice chest. No phone, no radio. Just God and me and the Everglades.
