I generally avoid the youtube video "experts", but there's one guy who is very professional, and historically & technically well informed.
His channel is called "capandball".

YouTube

He's from Hungary, and is an active competitor with their national muzzleloading team. He also buys and sells originals and repros.
Many of his videos are range comparisons of things like, say, an original Remington 1858 revolver and a Uberti reproduction.

Check it out. He's very informative and entertaining.

Best Regards,

PS: international muzzleloading competition has "original only" categories for most of it's matches. Lots of folks only shoot the originals!
