Own a "Deadnuts" stock .243 Savage Predator Hunter 10/110 Max 1 with a Vortex PST 4x16 FFP scope. I DO NOT hand load as of yet (I plan on it in the near future, but not at this moment) this rifle will be used for Coyote hunting. What would you guys recommend to be the longest safe distance for a humane kill, and what would you recommend for a good bullet/type/weight? If you have any other mods to suggest list them up plz.

Thx...
