Thanks Bob,
I'm in Ohio, so we don't have to shoot lead free bullets.
One of my .223's has 1 in 14 twist, I have several loads for it; 50, 53, 55, 60. I sometimes take it hunting for groundhogs and foxes in semi-tight residential areas and always wondered how good it would do on a coyote.
I think I'll steer away from it, just find a load with the same POI.
