Re: Leupold Help
14 power is a great fit for a hunting rig where weight, low light performance, & size are important. We use the 14X out to 1000+ for hunting & out to a mile on rocks and gongs.
If you are using a higher comb stock, chances are you will need to mount the scope at a height where 40mm or 50mm wouldn't matter. With a sporter stock, the 40mm close to the barrel usually feels more natural.
The advantages of 50mm aren't huge, but nice to have when lights fading.
If the rifle is primarily for range use, some more power is nice on way-off targets if mirage isn't too bad.
