Whitey's right: 7.5g of Unique is too hot to recommend using in Special-only revolvers.
It depends on which "Special-only revolvers".
The S&W 1950 Target .44 Spl., and later model 24 & 624, were the guns Skeeter used to develop & shoot that load in.
All the later N-frame S&Ws, from the triple-lock on, and all Colt SA's are perfectly safe with this load.
And no, they won't shoot loose in 200 rounds either!
They are like play-toy loads compared to what Elmer Keith was putting through his 1950 Targets prior to the .44 Mag.
I
would not recommend it for Charter Bulldogs however.
Actually, the .44 Spl. has always been
way under-loaded by the factory for some unknown reason. In any later S&W or Colt, the 7.5 grain Unique/240 grain SWC Skeeter load is what the .44 Spl. should have/could have been to begin with.
It is just a great plinking or hunting load in a Model 29 or any other .44 Mag!
