What a coinkydink! I just returned from my nearby range where I shot beside an editor from G&A working with one of those. Seemed to function fine, but was really loud, and he said that with the ammo he was using anyway, it seemed to throw one out of five out of the group.
Interesting, but not related, is that while we were at least six feet apart, his Labradar was picking up my .223 rounds, futzing up his data collection somewhat. Heard about a lot of Labradar quirks, but that’s a new one.
A Remington 600 cured Pappy of any foolish notions about short-barreled .308s, around 1971 IIRC.
