I was thinking lead just to get more spreading when it hits something as small as a coyote. Also, it would be gentle on an older barrel. Last time I had one going after a chicken I only had my 30-06 at hand and the fully jacketed round went through its chest without slowing down. Not a very quick kill.

Has anyone tried those lipstick rounds? How are the Rem rounds? This gun is an inheritance, so I want to preserve it and put big holes in coyotes.  :)
