The boys in Elk camp last fall up in ID laughed when I showed up with this:
and this (1.4 ounces). The tapered heel is because this is a hammered in bullet, as were the original patched round balls. Each rifleman (chosen man) was issued a mallet that hung from his belt to start the ball. When things got hot, they just spit the bare ball down the barrel, kept the muzzle elevated a bit and let fly. I've tried it with round balls and at 25 yards it would be deadly against massed troops. Not to say they were good, but to become a chosen man you had to hit a 1/2 man target at 300 yards from an improvised rest.:
but got real quiet on day two when this fell over at 18 paces (about as far as I could see in the jungle he lived in):
C. 1809 Baker British military replica, 61 caliber, 80 gr 2F, mold designed by me and made by Lee (pretty inexpensive too). Ballistics about like a 16 ga German Boar "deerslug". Double lunged him, he went 20 yards. MY guide's immortal quote was
"Holy s---, I could see the blood spraying out the other side when you shot!"
If you want to see Bakers in action, get NETFLIX and rent the 16 part BBC series Sharpes' Rifles where a lot of froggies have bad days with Wellington's boys in green.
