I was going to do this as a video but, umm... the battery went dead, so-
Just did a series of two shot drills on the timer, I was looking for:
Q: "How much faster can I shoot the .22lr vs 5.56 during two shot drills(double taps)?"
A: "Not much."
I did a series at 11yds and then repeated it at 5yds. Both carbines are basically stock.
Exercise: from the low ready, index the target and fire two shots, record the time split of the two shots. Repeat.
11yds w/ .22lr:
.18, .19, .18, .18, .19
11yds w/ 5.56:
.20, .19, .19, .20, .20
5yds w/ .22lr:
.15, .15, .16, .16, .15
5yds w/ 5.56:
.16, .16, .15, .17, .17
One shot is out of the 'A' zone, center left, it was one of the shots w/ the 5.56 at 11yds.
