Jason, 
here're some things you probably have considered already, but just in case, I'll attach a
Scope Specs Table below, with 60+ scopes in your magnification range.
All have 10y side focus,
all have a holdoff reticle,
all exposed turrets,
and most of them are under $500.
Some specs to consider and compare, if they are relevant for your shooting scenarios:
Is your field of view (FoV) wide enough? If you're target shooting, or hunting beyond 20 yards — no prob.
But for stalking and close range ratting, barn pesting, and shooting in low light your
FoV at the bottom end of the magnification is important ➔ to allow for quick target aquisition.
Every scope has a different FoV — even if the magnification is exactly the same, so check the specs if this matters. (A 4-24x, or a 4-20x or 3-18x scope usually
have a much wider FoV than the typical 6-25x, while still having a high top end magnification.)
You already seem to have decided on an FFP scope (my preference as well). However, if you are mostly a turret dialer (I am), then an
SFP scope will serve you just fine. This either broadens the options, or brings down the price.
If it is indeed a
FFP scope —
at low magnifications the reticle becomes very very small, and the crosshairs become hard to see to put them on the kill zone.
To help with that, many — but by far not all! — FFP scopes have
thick outside posts in the reticle. At low magnifications
those thick lines guide the eyes of the shooter toward the intersection of the crosshairs, and make aiming much easier.
As you are a turret dialer, for longer ranges you might want the turret to have
10mil per revolution (instead of 5 or 6) — as to avoid loosing track of how many turns you turned it up (sure, a
zero stop is a different way to avoid that, or a
turret turn counter).
If you mainly dial your turrets, you might not want to clutter your reticles with the myriad of holdoff points that a
gridded reticles provides.
As turret dialer, in case you're planning on shooting real long range, you might want to have
enough elevation adjustment available.... For example, some scopes only give you 50moa (and that means, 25moa up and 25moa down, unless using adjustable rings), so that's pretty lousy. With a scope with 80moa you can really reach out there.
➔ All these (and other) specs are listed side-by-side, with prices, warranty info, etc. in the Scope Specs Table.
Happy scope shopping!
