Re: Need help with a 308 round for coyotes in WI?
As for your .308 run whatever you've got that shoot's good. I shoot 168 bthp, and 168a-max out of my rem700 and get cloverleaf to one hole groups at 100yd and have been getting 1-1/2"-1-5/8" groups at 400yd so they're my go-to for about anything. They are both hell on deer and don't fragment bad, they tear yote pelts all to hell though, if not worried about pelts use your hand loads or buy straight from hornady last ones i bought I hot for $22 a box I'm thinking through midway, Black hills also makes some excellent .308 i like the blue box "reloaded brass" they're cheaper and the same quality as red box "brand new". As for .223 I run a 55gr v-max and it'll flat put them down from 20yd to over 300 I've got three with that load this yr already.
Best of luck and happy hunting,
