So does the .50 Beowulf which the case is based on. That doesn't seem to have dampened any interest in that caliber, nor ARs chambered in 7.62.
Are you referring to 7.62x39 or 7.62x51?
If 7.62x51, that's a different story - the entire bolt is much larger, not to mention the entire receiver, etc.
If 7.62x39, what interest? Those are not exactly in hot demand, apart from a niche.
States right in the first post it uses 5.56 AR mags...
Fine. I did state I was not sure of the mag. That aside, my other point
Non sequitur. Who mentioned trajectory of .300 BLK as being flat??
Nobody mentioned .300 BLK having a flat trajectory. Which is exactly my point. The post (yours) I was replying to asked why there was so much "hate" for this round, given all the love for the .300 BLK. Part of the answer lies in the ridiculous marketing terminology. These guys are mentioning "flat trajectory" in describing their round, while AAC is not using that term when describing theirs. To me, and others, that speaks a little bit to the integrity of the manufacturer.
So, I would suggest you look up non-sequitur, in order to see how it doesn't apply whatsoever in this case.
