Aw! Come on man! Everyone
knows that that may have worked for Davy Crocket but today's deer require 300+ grs of black powder substitutes ignited by 209 Nuclear primers and tungsten carbide expander slugs to be ethically harvested.
Doubt me? Just ask the professionals
that write in our and other hunting rags.
Last year I got a complete broadside pass-through at about 30 yds on a nice buck with a .490" patched round ball pushed by a "puny" 60 grs FFFg charge. The ball could was plainly heard bouncing through branches a good 50 yds behind him as well. I learned of the penetrating power of that .490" ball the first day I shot a muzzleloader. Got the gun for Christmas and a couple of months later took it shooting and started the learning process. After sighting it in ad realizing it was a lot more accurate than I'd been told for years a front-stuffer could be, I stacked up a couple of tightly-bound and throughly soaked phone books measuring about 3" thick each and backed off abt 20 pace and shot it hoping to catch the ball. Nope, plowed right through. Stacked up more books and fired. Again, plowed right through. Stacked all of my books, 7 of them in a line and fired again. I saw dust kick up several feet behind the stack as the last book fell over. Already knowing the result I looked anyway and yep, that poky little ball as the experts
often describe it had bored nearly straight through about 20"-25" of tightly bound and soaked phone books and kept on trucking.
This was from my CVA St. Louis Hawken cap-lock using the supplied CVA #11 cap igniting a "monster" charge of 90 grs of RS Pyrodex. No magnum load by any means. Over the years I learned that my guns and I shoot better with lighter charges and the deer have not seemed to notice the difference.
