So I'm an old school hunter with old school gear: rifles, scopes, etc. Don't own any of the new long range calibers: just old stuff: .270, .300 WM, etc. Low power scopes. So if I want to change from spot and stalk to spot and shoot, give me an idea of the gear I need to get started to reliably kill game 600-700 yards. Which rifles, calibers, scopes, range finders and give me a rough idea of what kind of money I'm looking at. I AM a handloader however. Sounds like I need a consistent 1/2 moa. rifle. I realize I will need lots of practice but just want to know the equipment needed. thanks
