These fellows are giving you some good advice. Far too much emphasis is placed on energy, to the point that even some pundits years ago promoted it in the, "event of a less than ideal shot placement".
An aquaintence of mine took a ninety pound whitetail doe at less than fifty yards with a 300 Weatherby and 150 grain bullets. The bullet struck the chest cavity with over 3000 fp's of "energy". The doe simply trotted off a few yards at the shot as if nothing had happened, showing not the slightest evidence of a hit. The shooter was about to shoot again when the doe collapsed. I share this not to promote the round ball over any other projectile but to illustrate that energy in not necessarily the answer, placing a projectile in the appropriate place is. Had this shooter not placed the bullet correctly that doe may not have been recovered. Would she have died any quicker to a roundball placed in the same spot. That could be debated around the campfire or the forum for years with no concrete answer. Energy is important in that you need enough to propel the projectile through the hide and the vitals, which roundball hunting loads from 45 caliber on up do possess. Don't get to caught up in the energy side of roundballs, they don't compare well in that respect to modern rifle bullets. Know, rather, that they have been used successfully on all manner of big game for centuries and are very effective when coupled with proper shot placement. Mart
