I have only killed two bulls, both with a 7 RM, both with the then new 140g Nosler Ballistic tip(old style). Both bullets were running, and at the shot both had their front legs fold up and their noses plowed the ground. One bullet kicked a hind leg a couple of times, the other never kicked.

So, would you guess that a ballistic tip is better than a partition?

Shots were 100-150 yards on a full out run, one broadside the other quartering to me.
