"No standard range I've heard of allows NFA Firearms."
Again, that may be true in Indiana, but it is certainly not true here. We have numerous indoor ranges here that all not only allow full auto weapons, but rent them. The only private gun club in town has monthly machine gun matches. I can think of a half dozen NFA dealers in this area right off the top of my head without even thinking hard.
The only reason I point this out, is because many people make broad sweeping generalizations on-line and mislead people who don't know any better. This stuff varies depending on where you live. What might be true where you live, very well might NOT be true somewhere else.
You know the rest. In the books you have read
How the British Regulars fired and fled,
How the farmers gave them ball for ball,
From behind each fence and farmyard wall,
Chasing the redcoats down the lane,
Then crossing the fields to emerge again
Under the trees at the turn of the road,
And only pausing to fire and load.
