I am in the process of purchasing a 6# 2 oz 338-06AI custom rifle and would like to hear your experience or opinions on what scope I should put on it. I am a nightforce guy mostly really like the ruggedness and click up and down ability. Not a Leupold fan. I am cautious about putting a 28-30 oz scope on it but like the 30mm tube, would like at least 15 power at top end as I believe this is a 500-700 yard rifle. What would you recommend people? I am older and think a lighter rifle may be pretty nice in rough country.
