Daisy 880. ....With Wichester 9.8 grain round nose pellets from Tractor Supply for about $5 for 500.

You can leave a pumper pumped. But it's not advisable to leave a springer sprung.

I have an old Sheridan Blue Streak.... if you can find one that works at a good price. Or for the price of a few Daisy 880's, a Benjamin 397 or 392.
FWIW, I don't like a peep sight on these. Just the standard barrel mount sight is faster and more accurate for me.

I really prefer a 20 or 22 for their ease of handling, and their impact on cans. But don't think it's necessary for your application.
