I have a Leupold VariX-III 3.5-10x 40 mm objective lens scope with a duplex reticle: virtually the same scope is on all my hunting rifles (my second .30-06 has a VX-III 3.5-10x 40 mm: a later generation of the VariX-III, I understand). The scope is perfectly suited to what and how I hunt. The limiting factor is going to be my marksmanship. Again, I rarely have long shots where I hunt elk. I'm not interested in training to be a marksman. I am a hunter not a target shooter. Also, I am not a trophy hunter but a hunter for meat and for the rich rewards of hunting in a beautiful place high in the mountains sleeping in a wall tent with a woodburning stove with good friends behaving as good hunters. I can and have passed on dubious shots in the past. I am a competent hunting marksman. I just don't know what the range limit on my competent hunting marksmanship is, because I have never probed that limit. I plan to establish that limit this year before returning to elk hunting.
