Hmm. Speaking of guns I can get another opinion!

My brother has 80 acres of land in western NY state. Part of a farm that was split up and sold off. He has 2-3 fields and also the former woodlot (with still intact hardwoods including some very nice old oak trees*.)

He plans to house build there eventually. He is also going to need a varmit rifle since he will be keeping chickens and possibly some other small livestock. Said rifle will need to deal with stuff up to coyote size. Any suggestions on caliber/type of weapon he should look for?

* - Downside of well-established untended hardwood area and that it has very well-established poison ivy with it. 3” think vines running up and down the tree trunks.
