considerations for squirrel optics and scope features.
like you stated you want something that you can focus close up to 10 meters all the way out to 100. forget about 50 or 100 yard fixed focus scopes.
2 options, you have the adjustable objective or a side focus.
I personally prefer the side focus because it lets me focus on the fly with my eye on the squirrel.
if you're a meat hunter I assume you are going for head shots and that's where magnification helps and a good ranging reticle comes in handy.
.22 can have a bit of an arc at those long shots and I prefer ranging reticles to help me hit that 3/4 inch to 1 inch squirrel head target.
my light weight squirrel gun has a vortex 2-7x30 side focus but my more "serious" squirrel getter has a vortex diamondback first focal plane MRAD reticle with a side focus. 6-24x50 30 mm tube
I don't really shoot it beyond 150 yards so glass was not the main thing I was looking at. what I was really interested in are the futures of the scope and they matched all my needs exactly. the price is just around the $500 mark as well. I love the fact that it's a FFP which helps me allot in ranging those tiny squirrel heads to be able to hit them at varying distances.
