I brought this topic back up with a little food for thought. I think some may learn something from this and others find this information interesting. Larry Kelly used a 200 gr bullet (208 gr to be exact) to kill a Bull Elephant with his 44 Mag..yes, the bullet was a bronze, tungsten core bullet, but it was 200 gr and penetrated the vitals of an Elephant. Depending on bullet material, weight is not always a limiting factor.
