Thanks,
From the placement of the cannelure, I would think that there would be room for a ton of powder. Enough to maybe get 1800 fps out of a carbine barrel.
Would the Hornady 180gr SSP bullet be reasonable for the .357 Mag rifle? The last two deer I shot with that bullet had two little holes each and it shot two inches @ 100yds from my .35 Rem Contender. Good bullet!
As long as we're not loading to an overall length dictated by revolver cylinder length, why not use a bullet of equal weight, but with a B.C. above .100? Just looking for options.
