Thanks for posting the video Currahee!
When I saw you doing the burpee's I broke out laughing. I was laughing not because you were doing 'em it's just one of the things that Mosby stresses. The first time I did them I was amazed at how much my gear didn't work. I kept doing them until I got it right and for the most part - I didn't sound like the flippen Tin Man.
On another note, I was impressed you were using a .22LR conversion or dedicated .22 upper for practicing! I thought I was the only guy doing that.
I am cheap and just don't want to waste my 556.
