2 rounds in 1.5 seconds at 7 yards would be very tough, but not impossible by any means. The rest is very feasible; the proper manipulation of a bolt-action should be measured in a fraction of a second. Or let me put it another way - someone with a stopwatch ttempting to "time" a proficient bolt operator opening and closing the bolt will have great difficulty indeed. It's that fast.From a low ready at 7 yards fire 2 rounds in 2 seconds at a ISPC Brussels target. For more of a challenge on the SERT course fire 2 rounds in 1.5 seconds. Or for more range. Go from standing to prone and fire 2 rounds in 8 seconds from 100 yards. For SERT standard complete it in 6 seconds. That is not going to happen with a bolt gun.
As Cosmoline points out, a bolt-action can be manipulated as fast or faster than most autoloaders can cycle, although this is no doubt significantly less so with small bores and pistol caliber carbines which might have faster cyclic rates. In the case of the leverguns though, this is pretty absolute.
I would doubt that most of those shooting in the described 7 yard drill are using anything other than small bore rifle or pistol caliber carbines. With the faster cycling time many are no doubt able to place an aimed snapshot, followed by a quick second based on a flash sight picture, and achieve an acceptable score.
Try that with a true medium bore autoloader shooting any load equivalent to military ball.
As an aside, two shot drills with a rifle at single targets seem alittle redundant to me, since the whole idea of using a rifle is it's decisiveness to begin with. Single round drills at multiple targets, widely spaced, and at varying distances makes more sense to me when applying a rifle.
