I dont think its too much. If everyone agrees a 6 power scope is enough than just turn your scope on 6 and we are all happy. Sometimes its nice to have that high magnification in the woods. Ive deer out there about 150yrds between tree's and if I couldnt have turned my scope way up(4x16 B and L) I wouldnt have been able to tell what it was.
The best point was that if you also want a good scope for shooting some groundhogs or crows way out there with that 7-08, you've got it.
I dont think you lose much ofthe F. O. V. with that compared to a 3x9 and not being able to turn scope to 3 wont matter much either. The biggest drawback I seeon a scope like that especially the Leupold is the difference in eye relief between the lowpower and high power. I have a 6.5-20 VIII and have to much my head forward and back when I change the scope setting. I have3 Leupolds and like them, but I notice that prob on them more then any others I have moving my head alot but you get used to it pretty quick.
