vt- I figured that was where you were coming from, but it is crazy hot here and I knew doggin was lookin' for entertainment as bad as I was, so I decided to play the devil's advocate. As far as how fast one animal is compared to another and how that speed is measured, there are so many factors and variables to consider that it is really hard to tell and you just have to have your rope ready when you ride over the hill if you really want to rope something.
So, vt, which is better for coyote hunting, the 22-250 or the 223? doggin done caught all the trout he can stand, he figures the handicappers will lead up him to much if he decides to rassle shampton and wants to know which cartridge is better. :>)
