I hope this will help you out, I have been shooting pd for 10 + years useing bolt guns but that is unimportant. My rifles are equiped with 6 - 24 power scopes and in the field one can seldom use more than 14-16 power for shooting but one can get some use of the higher end for spotting. Select a variable power scope to 14 power +/-, a simple reticle (mil dots are sexy but for this they are not worth the money as your ranges will not be all that great), and side focus.
