I use a .243 Win Savage Model 11 - Bushnell 6 x 18 power scope - haris bipod

for coyotes - I have found that the smaller grain ammo fragment alot more and does more pelt damage. I use 100 grain ammo and it seems to hold together better and passes through the animal with minimal pelt damage.

I have my rig sighted in dead on at 250 yrds. I am only an inch low at 300 yrds and an inch high at 100 yrds plenty sufficient for coyotes - but you'll want to tighten that up a bit if you're going to hunt anything smaller than a coyote -
