from the 1st shot to the last, probably took around 45 seconds, maybe 1 minute as the 1st got there a bit quicker than the next 4 did.
I also don't stop calling after I shoot one, especially now that I am shooting suppressed. I am convinced that it does make a difference, but I also know several guys that shoot multiples without suppressed rifles, so it's not a must. But since I've gotten my suppressor 4 years ago, the number of multiples that I shoot each year has gone up.
