You asked if I had to settle on one scope for rimfires, what would I pick? I already did.
This is a Hawke Vantage 4x32 AO with a mildot reticle.
https://us.hawkeoptics.com/vantage-4x32-ao-mil-dot.html4 powers are pretty much set and forget optics, but this particular model has proven to be versatile for me. I have two. One is on a 22LR The other is on a 22 Magnum.
The adjustable objective means that you don't have to worry about parallax.
The tracking is pretty good, and it has fully multi-coated lenses.
This target is a sighting in target. The first was low at about 7 o'clock. The second, a bit high at 12 o'clock. I brought it down a bit and put the rest into this cluster.
Granted, small groups are easy to make at 50 yards. For little rimfires, it's all I need.
