Re: I think im loading a little hot. . is this a sign
I believe that the 338 Whisper is built off of the .221 Fireball case and is intended to keep its bullet in the sub-sonic range to avoid the sonic crack that is typical of bullets that exit the muzzle above 1,200 ft/sec.
A 300SMK fired from the .221 case aught to have the trajectory of a tossed pumpkin. [img]/ubbthreads/images/graemlins/grin.gif[/img] A most interesting cartridge.
