Some will say "4-12 is more than enough for 50 yards", but I disagree.
I like to aim at a specific spot on my pests. Not just "the head" or "just the shoulder".
4-12 can't do that for me. Of course, I am different than most. I actually use my 4.5-27 on full zoom even at as close as 10 yards. I would do the same with my 8-34, but it only focuses down to 15 yards.
When I shoot out to ~93 yards, I only reduce zoom to about 24x because I need the field of vision to spot the chipmunks. Once spotted, if enough time is available, I still zoom in to the full monty, be it 27 or 34.
Yeah, I am the odd ball... but that's what I do. I like to be able to aim (if not always hit) a certain spot on my pests.
Aim small, miss small!
All my best!

p.s.
I almost always shoot from a rest of some sort. The Akela "lives" on the BOG DG tripod and the Fortitude is usually rested on some makeshift rest. I do make some off-hand shots out to 20 yards, but that is not all that frequent.
