Maybe someone has information on this or history but I was thinking and have a question.
The .300 Whisper though based upon the .221 Fireball, is being loaded in re-formed .223 cases, which allows use of the standard bolt. So, being a fan of the 6.8SPC, why hasn't someone used a .223 case re-formed to accept the .277 bullets, which would create a greater ease of transition to the 6.8? I shoot .223 and 6.8SPC out of my MSAR XM7-E4, I have the 6.8 bolt and .223 bolt and accompanying barrels and mags, but creating a 6.8 that uses .223 casings would mean no bolt or mag changes. Have I missed some historical occurrence, doesn't this seem like a better mechanical transition? I look at the measurements and case capacities and they seem to be close enough. Thanks for any input.

300 Whisper is based on a necked up .221 case; it's easier to cut then neck up a .223 case, and the head dimensions and body tapers are identical between the Fireball and the .223 Remington. And there's a WHOLE LOT more .223 brass around than .221 brass...
So why not a necked up .223 case that handles a .277 bullet? There are several; the .277 Wolverine, mentioned above, is one. So far none of them has gained a lot of traction, so they're not as "visible" as other rounds. |
