Going to build a rifle. (probably a Jim Chambers kit but open to suggestions). Going to make it both flintlock and percussion since I like the flintlock look but think percussion will be better for hunting. Will only shoot round balls due to the barrel and the drum for the percussion. I do not anticipate hunting with it personally but hopefully someone will down the line. For deer hunting with a PBR how do these calibers compare? Or is a .54 better yet? Probably going to be a 38" barrel if that matters. And the catalog says that it will weigh about 8 lbs in .50 cabler.
