DO: Make sure your action and sight screws are tight. Ditto bases and rings if shooting a scoped rifle. Sight in at 25 yards first; easier to get on paper. If you're dead on at 25 yards, you should be on paper at 100. Generally speaking, I sight in 2 inches high at 100 yards, which will let you hold dead on out to 225 with most centerfire cartridges.

DON'T: Waste a lot of effort shooting and cleaning to "break in the barrel." Unless you are working with a custom barrel, it isn't worth the effort. If you must break in the barrel, clean it; shoot five and clean, repeat until round 20. You're good to go.

cogito, ergo armor
