Have my first 41 mag headed my way, a 4 5/8" Ruger BH. Found it on a forum the other night at a price I couldn't pass up, so I jumped on it. Ordered dies tonight, also found a 550 conversion kit for it on a FB page and it should beat the dies here. Just looking for opinions on this round, having never fooled with one so far. Also, does anyone know of a place in OKC that sells cast bullets or brass that would fit it? Thanks!
