I use a .223 T/C Contender. Topped with a Simmons 4-12 44mag scope. I use 55 gr. Hornady ammo in the V-Max line. Gonna try the Superformance as I can get some in. Also you can practice with super cheap Wolf ammo in the same weight hollow points. They have shot actually better groups at 100 yards than Hornady, but once you get to 150 they start spreading out. But still plenty accurate. I have not checked Ohio regs, but read them well. Here in TN, we can only hunt coyotes on public land with another open season and them with the type weapon used for that season.
