Hey guys, I am looking at maybe getting a varmint rifle to shoot some coyotes around my neighbors cow/goat farm. I have narrowed it down to either getting a .204 or a .223, my local walmart has both calibers in H&R single shots for about 260 dollars. Ammo is also about the same cost . Which of the 2 have more killing power? What is the max range of a .204 and a .223, So which one would you get?
