I read an article a while ago about a former Force Recon Marine that now teaches at some shooting academy. He teaches to shoot rifles after breathing in and then exhaling all air from your lungs. Apparently this is how Force Recon teaches rifle shooting. Prior to that, I thought you were supposed to inhale and then exhale 1/2 your breath. I have heard this from people with military background. If FR is teaching to shooting empty lunged, it must be the best method. Is anyone familiar with this or do you only shoot empty lunged in certain scenarios? Just curious. Thanks.
