I dry fire a lot also. I developed a flinch a while back, moved up to a twelve gauge when i wasn't ready. Wasn't long before i saw it affecting my rifle shooting. This was before i was serious about shooting though, i noticed i missed deer which bothered me, but it wasn't until i really got into shooting that i fixed it. Technically i still have a adrenaline rush and anticipation of the rifle going off when going to through a slow pull. But mind>matter and i just follow fundamentals. It's more noticeable when I haven't shot in a while. Versus shooting every weekend when i was closer to home last year, which was nice. Was so used to the trigger pull of my .308 followed with the same recoil impulse i was watching my shots through my SN-3. Dry firing in the dark helps even more.
Then I heard the voice of the Lord saying, "Whom shall I send? And who will go for us?" And I said, "Here am I. Send me."
