I'm amazed at the penetration of the .36. I have a farm and on occasion we have livestock die. I have shot a conical over 17grs. of 3f right through 15"+ of carcass and didn't find the ball as it went through over 2' of snow. the same results with the RB but the wound was more pronounced with a cleaner edge where as the conical wound channel looks as if it was made by a .22 it must just sort of slip through the flesh. I did recover one conical in the snow about 18" in that hit 2 bones and went through about 15" of flesh. didn't even flatten.
I am looking at my old lyman 45th edition and in the back it has a load for the .36 Navy 51. .375 RB, No. 11 Alcan caps, 25 grs. FFFG DuPont Black Powder. Vel. 1005 FPS.
No. 37583 145 grs. conical bullet, 15 grs. DuPont black powder, Vel. 690 fps.
It goes on with the .44 Army Remington.
.451 round ball, no. 11 caps, 39 grs. DuPont FFFG black powder. vel. 995 fps.
no. 450228 conical 155 grs bullet, 26 grs. FFFG DuPont black powder. Vel. 815 fps.
Seems they are effective with the round ball and the .44 conical as well. However, as stated many times above, one must hit a vital area.
I believe Wyatt Earp stated a shot to the belt buckle area was effective.
