Squirrel Scope

So with all the squirrel threads it reminded me that it is squirrel season.
I took the .22 out to the range and it is grouping nicely but I could not get the Burris 4x scope to focus well. It ghosted the reticle when I got it close to focus.
What would be a good economical scope to put on a 10-22 for squirrel?

Well, the rifles value is about $300 so something like that.
I have always been a firm believer that when possible the optics should cost at least as much as the firearm they’re sitting on.

Thank you all for your well thought out replies.
I remembered I had a 4-9 Bushnell in a box and put that on. It zeroed about 2 clicks from max vertical and in shooting it would randomly jump the poi about 5-10 moa. The funny part was the gun would shoot cloverleafs at 100 yards then it would jump and shoot cloverleafs again at the new poi.
I retightened everything, even reversed the rings but it acted the same.
Just as I was about to pitch the whole thing in the trash barrel I remembered my LGS was still open.
I scurried over there and the decision came down to what the LGS had on the shelf, which was a Bushnell AR optics 4-9 with side parallax and RTZ turrets. I’ll have to figure out how many clicks per 50 yards with .22 again.
The LGS heard my frustration and gave me a deal on new base and rings cuz I just had no confidence in anything that was on the gun.
When he asked if I wanted the old scope or hardware back I told him to give them to someone he didn’t like.
I scurried back to the range at multiples of the speed limit to get there before it closed.
The end of it is that the rifle once again shoots way better than I do. The squirrel population is in trouble.

Here is my Bushnell. So far I am quite pleased. Still trying to figure out the maths for the reticle.

If anyone knows the math to convert drop point yardages for different magnifications please feel free to educate me.
