Cranky, the options are vast...! That's the beauty of it!
(A) As you specify hunting out to 100 yards, well, then the
top end magnification will be critical. A 12x at the top end probably isn't going to serve you well. A 16x or 18x magnification would be the minimum I'd consider. And for older eye, get more... (20x, 24x).
(B) Are you also stalk hunting, where game can pop up at 10 or 15y and you need to take a quick shot? Then the bottom magnification will also be important, or rather, the
field of view (FoV) at the bottom end. A 15ft FoV (@100y) is going to delay quick target acquisition at such close range. A 25ft FoV would be much better.
(C) If you've decided for an
FFP, a reticle with thick outside posts would help guide the eye toward the cross hair intersection when at low magnification. (I personally consider this critical for an FFP).
(D) You didn't say much about weight. You did say you're interested in a compact scope. But
long range shooting and
short length scopes are diametrically opposed to each other...
-- so, you'll probably make a compromise.
(E) Are you OK with a
gridded reticle (Christmas tree style)? Because a growing percentage of FFP scopes have it. (Some can't stand it, some won't buy a scope unless it has a grid.)
(F) Is an
illuminated reticle important to you?
(G) OTHER features to consider: If you are a turret dialer, and you're shooting out to 100y, you might like a turret that gets you to 100y within ONE revolution of the elevation turret. The better scopes (with higher magnification) often come with turrets that don't just have 5 or 6 mils per revolution, but 10 (or 12) mils. Very nice!
Some come with a zero stop.
Some come with locking turrets.
Some come with revolution counters.
To make comparing the specs of different scopes easier, I made
Scope Specs Tables. I'll attach two below.
Now, once you come up with some models that have the features you like, ask our scope glass specialist
Odoyle if he has an opinion on those models. He seems to know glass like no other.
Happy scope shopping!
