I'm not a scientist , a chemist or a mathematician, I just go to the range and shoot .
I went through a phase where I was obsessed with getting Slugs/Nessler Balls to shoot out of my. 69 Smoothbore, I finally cracked the code and fired a 6" group at 100 with a Smoothbore musket shooting Lee Slugs. After using different powders, caps etc
Ok, cool....I can use round balls , whatever powder I can find or feel like using and CCI musket caps and shoot 8-10" groups. Who cares, the paper....the deer at the range? Old Indian Ghosts
I'm not a formal competition shooter
There are so many variables to shooting, I don't have the time to shoot 3x a week or the ability to keep obtaining Swiss powder and RWS caps, to maintain a 2" group with an Italian repro Hawken
It depends on your needs. This is all supposed to be fun, so don't forget to have some
