I play around with light bullets sometimes, but for hunting big game, I prefer heavier. The problem with light bullets, one never knows if they may need to take an angled shot. Requiring more penetration, than a desired broadside shot. I'm kinda "old school" yet, and still believe in momentum, rather than "energy dump". There's a saying, energy expands the bullet, penetration kills the animal. I believe one only needs a small degree of meplat upset to impart "hydraulic shock", but momentum imparts more damage to the CNS.
Enough rambling, ya I like exit wounds.
