I've set my Leupold VarX-III 2.5x8 on my 30/06 at 3" high 40 years ago. It's killed everything I shot at. Never had to reset or adjust. Use the same 180 grain load for everything. Simple
Yep
Know your rifle and how to shoot it.
WTH did we do before technology took over "hunting"? I guess all the deer and antelope I got dropped dead, laughing at my '06 with a K 2.5 and later a K 4 on top.
