RE: Savage 99 .308 - scoped or peep sights?
Scopes are always superior, BUT use a QD mount, and put a receiver sight base on it that you can slip a slide into and have an instant peep if you need it. I'd use a Lyman 66 on the rear, and a Rdefiled Sourdough type blade on the front. A good peep is plenty good enough out to 250 yards, IF you can plainly see the game animal.
