I agree. While I enjoy my BP firearms, they are ancient technology and those who depended on them back in the day often carried more than one in case of a jam or mis-fire. If I have a serious situation where lives are at stake I will reach for the most effective modern weapon available.I'm told muzzle loading weapons did kill an estimated 600,000 Americans during Mr. Lincoln's war.
Nevertheless, when protecting my one and only life, I carry a nice S&W cartridge revolver.
There are reasons why self-contained cartridges have been so popular for a century and a half now.
