Very true statement. I remember during my NRA training, I was able to shoot and hit the target fairly accurately. But during one session, the instructor fired shots in the air (without me knowing he was going to do that)...I was alarmed and I could not hit the target. Point taken. When stuff is actually going down, I pray I do the right thing.
Please don't take offense because none is intended, but... Say WHAT??
I hope you're mistaken about this and that your NRA training instructor was firing shots into the ground somewhere.
Firing a handgun or rifle into the air is a BIG BIG safety violation. That bullet's gotta come down somewhere, maybe a mile away...
(Please don't do this at home...)
That’s when training takes over. The breathing, repetition, muscle memory is to overcome all that.
