As noted in John Ross's "Unintended Consequences", (sorry I don't recall the actual page number), John Browning had Ad Topperwein demostrate the BAR to the military.
IIRC, Ad cut 20 - 1/4" thick 2" barstock disks and had a tosser step 25 paces away. He was instructed to toss the disk into the air, perpendicular to Ad and toss the next disk as soon as he heard the previous shot until all 20 disks were tossed.
Ad hit 20 for 20 and after the military folks had done all their ooohing and ahhhhing looking over the retrieved PERFERATED disks, Ad sent the tosser back to the same spot, except this time the tosser was instructed to toss them into the air sideways. So Ad was aiming at a 1/4" wide by 2" high disk when tossed. He hit 18 outta 20 that time.
This was all done off-hand with a standard BAR.
Needless to say the military was mightly impressed, btw, if you haven't read the book above I highly recommend it.
