Well, you can always get a better rangefinder and a good spotting scope later.
I would go with a more compact scope and the NP-R2 because I am accustomed to working with MOA rather than MILs just as Eddybo stated.
What subtending system are you most comfortable with?
Making calculations and doing conversions in the field is a LOT more difficult than sitting at your computer and doing them.
Hence, I would also recommend shooting your rifle and collecting drop data for the actual ammo and environmental conditions you'll be hunting in and having custom BDC turrets made. Kenton Industries
If you hunt a wide range of altitudes and temperature, you may need more than one set of turrets.
If you're not already familiar with that system, you should study up on the Huskemaw scopes and their methodology. Even if you think their product isn't up to your standards, the methodolgy is very practical. ...especially if you hunt without a good spotter to help you range, dope the wind, and calculate scope adjustments.
