In my opinion the goal for coyotes should be no billet exits. If you consistantly do this, you will save fur if you are interested in doing so, and kill quicker. For me calling coyotes, that is why I prefer the .204 and the vmax or berger bullets. I don't like thru and thru's because they run farther. I had way more runners with my .25-06. I know there are a ton of reloaders out there that have a formula for the .243 to get an entry and no exits. I am not one of those guys, but that should be the goal you wok towards.
I should have added that the dog I shot last week with the 70 grainer made a smalll hole on the exit side, no blow-up, just a bullet sized hole.
