Yes, flatness doesn't matter at the max range that either should be used on these two selected targets(animals) you 've chosen. Precision is paramount on bullet placement of either one of these calibers.
Byron South explained to me about shooting bobcats, hydroshock has very little bearing on these guys. If you ever skinned one, you'll know what I mean. They look like weight lifters once the fur is off. Thick, dense,solid as a rock. But either of the two calibers is pretty decent on fox if ranges are short, 50yds and in, no fur damage-dependant on bullet selection. Still get a few runners with either. Stay on target for follow up shot.
Go on and try some out.
