Any suggestions on air guns for yotes

You won't be able to find anything cheap that can get the job done. Probably the cheapest would be a .25 Benjamin marauder but you're looking at headshots only and ideally 35 yards max for a clean kill. Another alternative might be the .30 Hatsan BT65. Lots of people complain about the drop-off of .357 and bigger. Probably the cheapest you could go is like $500+.

Can't find anything cheaper that works. The cheapest option is probably the .25 Benjamin Marauder, but it could only cleanly kill someone with a headshot from 35 yards or less. The .30 Hatsan BT65 is an additional option. The drop from .357 has attracted a lot of criticism. The cheapest you can go for is probably $500 and up.

What distances are you considering? are you calling them in? More info would help.
