I guess I'm kind of going backward. I started out with the civil war replica pistols ending with a Remington but they were so much work loading, cleaning and being careful to watch out for hot caps dropping on my hand when I cocked it for the next round I sold the whole works.
Rifles are much more useful IMHO since I only get to the range a few times a year now and mostly hunt.
It seems you have done experimenting ..... BIG TIME. You're dead on for the CVA so am sure you've got the TC nailed in regard to what groups good etc.
