ihmo - Bullets are for ctgs. or for competition at long range in purpose-built muzleloading rifles, not for muzzleloading hunting rifles. Round balls also kill game faster than conicals seem capable of. Higher impact speeds, flatter trajectories and they projectiles that don't come apart. The pure lead is like an adhesive, expanding, yet sticking together.

Conical bullets were invented to fill a need when militaries around the world decided they required projectiles to kill or wound humans at longer range than about 300 yards, thus conicals and faster rifling twists to stabilize them were developed. Wounding become just as important or even more important than killing due to the manpower necessary to remove a wounded soldier being extracted from the battle. This wounding capability is what conicals seem to do the best.
