Hey halfrack, I have the rem. 12g. mag that takes the 3.5 in. with a mod. choke. I shoot the 3.5 in. dead coyote loads. It"s" T" shot, I have never missed a coyote with it. You can take one out to 60 yards, no problem. Some states do have laws on buck shot so ck it out. What ever you decide on do pattern the gun, as all guns shoot differnt loads differnt." If you do go with the dead coyote,,, dig deep, they don"t give them away. I think they are worth it . About 2 bucks a peice.
