The .58s are monsters, more or less. We take Dragoons and Walkers, make them
solid frame like an overgrown 1858, new internals, new cylinder out of
top-quality steel, new barrel (made in house), etc. Recoil is stout, as you can
get up to 1200FPS out of a 440 grain bullet - the revolver itself can go much
higher than this, but the bullets pull out of the chambers with any more recoil
than that.
The conversion for either a Walker or Dragoon is $1,255.00, plus either a
revolver from you or the cost of a revolver from Taylor's.
Do note that we can do a similar conversion to ROAs, but it is much more
expensive as there is quite a bit more reworking to be done - $1,750.00 is the
base price for that.
If you're interested, we also do .50 conversions on ROAs for $995.00 and on
Walkers and Dragoons for $819.
