Of course I would favor that 123 grain soft point, driven fast. But lacking that, I would favor the 160 grain Cast RN. Any way of Hollowpointing it or cutting an X in the nose?
BTW, saw what some coyotes did to a calf that was still being born...my warm fuzzies about 'yotes are all gone.
Had to shoot one two years ago that charged me. I had already drawn on him when he decided to come after me.
Some of the local "yotes" have lost their fear of humans.
I mostly use a .223 with a 52 grain CCI/Speer FB-JHP over either W748 or H335, when hunting Coyotes, but I have also used a 7x57mm Mauser.
I've read that the .22 Magnum can be effective on Coyotes, but I've not tried it as yet.
