What revolver will you be shooting these bullets in? A .38 Special (only) revolver or a .38/.357 magnum? That's an interesting bullet. You can load it down for very mild recoil, say around 750-800 fps in .38 spl. Or load hot in the 1200-1400fps range in a .357mag revolver. Roll crimp the bullet in the cannelure. This will give you the correct OAL. You can achieve either the mild or wild loads using either Titegroup or HP-38.
