I used to really enjoy hunting ground hogs. .22-250 then sorta downgraded and used a .223.
Still good go 300-350yds. And our gently rolling farmland here made for some fun shooting.
They used to be everywhere. Spring/early summer when beans were just a few inches tall, you could see everywhere they were active. Large dead areas in the bean fields around their holes. And half-circle areas along fencerows. Just ride around in the atv and spot one a few hundred yards away. They usually werent scared from that distance, but easy enough to reach out and touch them with a high power .22 caliber.
Now....they are scarce. Hardly see them anymore or even see signs of them in the fields. And when you do see one, they keep close to cover like old barns and structures. Coyotes have really put a hurting on their population for sure
