I called Dave Kiff to ask on the reamer print my two 300 whispers are built on. He said the print number is the same for mine as the blackout. I guess I picked the right one......so I guess the difference is the Blackout starts with the letter "B"
I appreciate there were numerous chamber variations in the wildcat days. It is cool for all the new comers to get a standardized chamber with the Blackout.......but it is still 300 Whisper. Mr. Silvers likely has smoke rolling out of his ears on that one. Not arguing he deserves credit for submitting the cartridge through SAAMI. Not arguing that the recent burst of interest will help a great deal of us in new products being available.
Since the Whisper was never a SAAMI spec cartridge, I fail to see how one can apply the 556 vs 223 argument. The whisper was whatever the end user made it. The difference between my chamber and a blackout chamber is less than what difference you will find in individual gunsmith's preferences in verification of head space.
JD had thinner necks due to his use of the 221 case necked up. He decided to be grumpy and keep it exclusive. The rest of the world went with 300/221. One can argue the difference of the chamber's between the two, but it still is within most manufacturer's range of tolerance.
I own a S&W revolver in 45 Colt, a Ruger single action in 45 Colt, and a Marlin lever action in the "same" chambering. Throat sizes are different, and if one wants accuracy out of each with cast bullets, you size to a different diameter. The Smith and Marlin have loose enough chambers that I keep the brass separate. Should I start calling them 451 Ruger. 452 Marlin, and 453 S&W?
My Ruger MkII won't feed CCI subsonic to save its life. My BRNO Mod 4 eats them great. I guess one isn't a 22 LR?
If it were me, I'd use the chamber reamer everyone else is using, and have the barrel marked "300 ilike2hunt2", and you can make it your very own, just like everyone else has.
