338 Whisper #2
I've found references to a 338 whisper #1 built from 7m case and #2 form .221 fireball case. But I have never found any barrels or reamers or any info on building a #2.
A #2 from .221 brass would be nice becasue then it would fit into a complete AR15 platform. The problem would be that there would be no shoulder to headspace from and headspacing would have to be done from the rim.
Is this a big enough problemn that no one does anything with it anymore? Since it's subsonic I don't think accuracy would be a great concern for being able to hit at great distances.
Is the #2 basically non existent now? What problems come from not having a shoulder? Is there anyone doing anything with this cartridge?
