Well number 1, I have used a REAL M21. My guess is you haven't.
How is that for starters? But whatever.

# 2 Machine gun ammo the most accurate? Damn I didn't know that, it must not have been available to me or any team members.
I've shot enough Match, Special Ball, and regular ball to fill several decent sized bins, but I guess you having been to all these, events, where all this knowledge was dispensed puts me in awe of all you know to be fact, and my EXPERIENCE must be flawed.

I actually had the misfortune of carrying the M14 SAW back in ranger school. I didn't realize that I had a match grade sniper rifle in my hands at the time.
Oh well, good luck.

When people face the possibility of freezing or starving there is little chance they are going to listen to unfounded claims of climate doomsday from a bunch of ultra-rich yacht sailing private jet-setting carbon-spewing hypocrite elites
