Gentlemen, As a reenactor, I dont know how many of you have ever been involved in platoon volley firing of 5 or more henrys? I have been involved once and seen it done one other time at night. I guarantee you it is an entertaining and crowd pleasing experience, particularly the night one!
I think the secret is rather than everyone firing on an individual basis(ala John Wayne style), Have an officer or nco command it with "Ready , Aim , Fire " at a 5-10 second interval and unload 14 rounds in 1-2 minutes.
Hope you can find enough henys to pull it off. It is impressive!
