Kaido casts his a little hard. I assume they don't expand as cast per him. If they were pure they might expand a little, and to get that level (complete passthrough) of penetration may require a little more velocity.
I view things from a more extreme perspective. Hogs may be common in the 150-250 lb range, but it's not unheard of to run across one that's 350 lbs.
I'd probably mess myself if I saw one of those Hogzilla monsters! I don't know if I'd shoot it with a camera or my rifle! Not the pistol though!
