You'd be most welcome over on the OT BB , if Hoof or the good General wanted to transfer this post....
I'll offer my insight & 2 cents , having shot C&B & conversions forever
The Walker is the biggest bad-est of the lot, but with it comes some things that might detour you....
1. it's weight just over 5 pounds loaded, is less desirable as a holster carry gun , pretty healthy tug on your gun belt all day
2. The hefty loading rammer, has the early design spring keeper, rather that later( Dragoon) design catch... it has a penchant to drop down on each recurring shot ...annoying !
Course these are work a rounds.... but , for a new comer ... be just enough to sourer the experience.
I'd recommend, a 51 Navy in 36 cal.
( skip the never was 44 ) or my personal favorite the 1860 Army ...both saw extensive use in The ACW and the WEST ...
and by all means skip these in brass frame Both are great holster carry pieces, Newt carried a 51 Navy , and Pea eye had a Richards conversion ( Lonesome Dove connection )
Get yourself a powder flask , ( skip the plastic starter one ) a Slim Jim holster and I believe , you'll enjoy the experience, then when your hooked and ready ..get your Walker....
Oh, and expect to want a Henry to go with them
