Anyone new to this black smoke stuff would do well to start out with a Remington .44 . The one's that Cabelas sells is in the Pietta model and a damn good one at that plus Cabelas stands behind everything they sell 100% and they take care of there customers.
The Navy Colt would be my next best and will be soon
It's a little more work to tune and and that's one of the reasons for starting out with the Remington. Easy to tune and lot's of info and advice on them here and on other sites and books.
Whatever you get don't be afraid to ask questions on here and it's a good idea to ask before you try anything your not sure of. We may not know it all but we will help in any way we can and help you do it safely. Now if I had as much money as the other guy's on this site I would own lot's of fancy BP revolvers but I'm just a poor dumb old man that these guy's like to pick on
Just kidding!!
Good guy's on here and they are all willing to help , just ask.
