Frog
On the 357, I have a booklet that was put out by TC, that shows a load of 9.0 gr. Hercules Bullseye, small pistol primer WW or Rem. Bell case, load powder, insert flat end of capsule into case, seat capsule and crimp.
You need to shoot these with the choke installed to stop the spin of the capsule.
My first barrel was a 44 hotshot barrel. Took a few squirrels with it. About like a 410.
