My video seems to depict two buffalo shot once or twice with the .44Mag and they would've been down for good had we not pushed them. Sorry but I don't see a marked difference between them when the bullets break heavy bones and reach the far side. A .44 hole through the heart is just as effective as a .500 hole through the heart. I have ALWAYS contended that bigger was better but the things I've witnessed have led me to question that conclusion. I think they increase the odds of a quicker end but do not guarantee it. Bullet construction is far and away more important. None of my bullets experienced "epic failure". In fact, they did quite well. I do not expect a cast lead bullet to fully penetrate a large critter and break heavy bones without deformation. Mine performed as well as could be expected but clearly illustrate the limitations of cast bullets. Others did experience "epic failure".
