I just want the coyotes gone so mostly I use 55gr 243wssm, also 52 gr Amax fron 22-250. 22-250 doesn't have the range of 243wssm. Neighbor took a coyote chasing three does with his 7mm 150gr and his grandson killed a coyote chasing two does. I only know of two coyotes left around my place and they have been to school. I know I have missed both on at least one ocassion. I need a new trick. That is one reason I am using the longe range predator gun, the 243wssm. BTW if I see one from my house he will get the 7mm 168 Berger, even more range.
