Guys, Thank You for your responses. I spoke with the folks at Corbon earlier this week, they told me that the .300 Whisper is pretty much a "handload only" round right now due to the "war" and their supplier only making .223 rounds on their machines. So much for Corbon making thier own ammo. They DID tell me that they are trying to find another manufacturer to produce the 150 gr. loaded rounds. Midway has already removed the .300 Whisper Corbon loaded Ammo from the website pages.
Can you help me out, as I haven't started to reload this round, yet? Is their a source of formed brass, primed or unprimed?
Thanks, Joe
