Took a HRA pistol skill builder (SB) yesterday. It was fun, we shot steel 100% of the time. From distances 7 yards or so. We did under vehicle simulation shooting heights, shoot from behind cover/concealment, and all were at steel. Which I really enjoy because I like to hear the ping. Things I've learned
1) When reloading from behind cover/concealment, don't keep yourself sticking out. Go back behind it and reload there. Then pop back out and shoot, and if possible, don't pop out from the same spot, keep the bad guy guessing where you will be popping out from. Also factor in if there is a threat above you, because that may determine how far back from the cover you will be shooting from (depth).
2) I dry fired shooting from my back, but never had the opportunity to do it live. And when dry firing, it was a straight shot. We did shooting from behind a barrier (cover) on our backs. So when shifting from left side to right side, be aware of your knees/feet. You don't wanna shoot them. Vs. shooting straight, your knees and feet are spaced out to your left and right, so not much worry.
3) Gear placement is fine doing these new things. So no change needs to be done.
