Put a new scope on my old .30-06 bolt-action, thinking I'd have to adjust for days, but found it was nearly dead-on after just three shots. Reminds me of my service days: sometimes the simplest setups work best, as long as your basics are solid. Anyone else keep it straightforward at the range, or do you prefer bells and whistles? Less is more, ain't it?
