For cost one does not need to jump in the deep end of the pool right off the bat unless they have no other way.
My own setup at the moment is;
Two Pietta 1873's - one used that was $400 and the other new for $525 - $925
Rossi/Puma Win '92 clone. $600 With gunsmith slicking up call it ------- $800
Biakal SxS which I cut down and filed off the ends to 20" barrels --------- $280
Mexican made gun leather which is now two years old and doing fine ---- $120
Total - $2125 OK, add on another $15 for the cowboy hat I found at Value Village to round it up to $2140...
I know the rifle is holding me back a little. But it's all for fun and I do enjoy tinkering so I'm going to keep trying to make the Rossi work better. Some would argue that the Win'92 actions are not the best setup. And at least in .357 I might just agree. But I'm not done tinkering with it yet...
But it also shows that one does not need to go overboard if they want to keep the costs of cowboy action shooting a little under control.
