I just bought my first black powder weapon from Cabela's, just north of Ft Worth. I bought an 1858 Remington, pietta, steel frame, and it is a great piece. I've fired about 100 rds from it so far with no problems. Fit and finish is very good, and its as accurate as any of my modern semi-autos. Cabela's is a "one stop shop" for these weapons, as they have holsters, powder, primers, ball, flasks, and pretty much anything else you want. I was impressed with the customer service I got at the gun counter, everyone was very friendly and patient with my questions. Good luck beating thier prices.
