I have a bit of trouble with that data. The cyclic rate there is 360 rpm....full auto in some guns.
A trained pistol shooter can sustain aimed fire with splits of easily 0.20 seconds. That's five shots a second. Yes, it is equal to or close to the cyclic rate of some of the slower sub-guns like the M3.
I've shot aimed splits under 0.15 sec., though not a full magazine of them in one string.
Aimed fire....nine trigger pulls with ball ammo and recovery from recoil in 1.5 seconds.
Sure. My ammo is 200 gr. SWCs at 850 fps. Pretty close to ball ammo specs. Certainly no powder-puff load.
Now, what's not stipulated is a draw, or type of holster, or concealment worn, etc. That's just pure rate of fire. Most good shooters can achieve a 1.25 second draw, and some can get under a second. Add a second for the draw, and then 9 shots and you'd be at 2.5s or a little under.
I'd not included that time as I don't know what kind of carry rig the Sebu-toting shooter would need to use, but I can't imagine it would be as fast on the draw, and certainly isn't as fast to get off safe, as a traditional handgun and I didn't want to artificially put him at a further disadvantage.
I would dearly love to see that. Maybe there is a video - not yours necessarily - of some one shooting ball ammo that fast and accurately.
I have seen seven in 1.1 seconds so perhaps nine is doable ----
I'll look around. Most good shooters demoing pure speed are shooting "Bill Drills" but that's only six shots. (Here's a fast fellow:
http://www.youtube.com/watch?v=NpKv6TJMq0Q Draw and six shots on target in 1.11 sec. If his draw is only 0.5 seconds, his splits are a bare hair over 0.10 sec!)
but for the average shooter, I think not.
Now I
never said an "average" shooter. The average is very hard to determine, as the "average" shooter might be anyone from a deer hunter, to a bench-rest shooter, or silhouette shooter, or Grandpa who just loves to take the kids out back with the .22s to plink at cans. I wouldn't expect this from someone who is not an experienced pistol shooter who has some time behind the trigger practicing this kind of thing.
'Course, hitting much, quickly, with a Super Shorty is also not for the untrained, either.
