Iv got the Parker Hale 1858 2 band Navy rifled one. Brilliant bit of kit. Mine prefers patched round ball but will shoot mini bullet as well. I use black powder only in mine but i believe you can use a substitute such as 777 or pyrodex aswell. Had it for about 8 years and its still worth what i payed for it if not a bit more and it still gets used on a regular basis. Only down side i know of is they are sighted for distance shooting and as i often shoot mine at 50m the sights are adjusted right down so your cheek is on the stock, 70 ish grains of b/p soon makes its self felt.
