I do not muzzle load, but I really would like to. I think that a traditional rifle would be great fun. I have always wanted a kit where I could finish the rifle myself.
You should give it a try. It's loads of fun. Despite what some people think. You really don't lose much in the way of power or accuracy with a black powder gun. The only difference is you only have one shot.
Years ago I was reading a article that Hank Willians jr wrote about shooting Black powder vs smokless in a 45-70 or 45 something like 70 or 110. It was a good read. He shot a life size bufflo made from a steel plate at I think 900 yards. He could hit the bufflo most of the time with Black powder loads and about 40% with smokless. Like I said it was a long time ago. But I do remember how the BP shot better. He even let his wife shoot the target and she hit it on her first shot with the BP.
I know of a guy that shoots BP competition. I went to range with him a few times. I can't out shoot the guy at 50 yards with my modern hand guns. he shoots BP hand guns as well. I always thought I was a fair shot with a hand gun!
I have Ruger Vaquero stainless in 45 colt that I load with BP. I use 25grs of 3F BP and I will tell what. It is not a wimpy load. I seems to have just as much power as smokless loads. The BP just makes a mess of my gun. Before I get to 50 rds I need to clean the gun. I'm pretty sure thats why we use smokless today
