Give them the gun empty, but let them think the gun is loaded and ready to fire. Watch them when they pull the trigger. Almost guarantee there eyes shut completely and they flinch....some experienced shooters do this but they have learned to compensate for it. New shooters dont know how to deal with it.
Very true.
To add to that, try loading the gun for them a few times and handing it back to them, all the while trying to build confidence in them each shot to breath normal and SQUEEZE. Then, slip in an empty casing. When the gun doesn't fire, they will sit still for a few seconds wondering what just happened, thus giving you the perfect opportunity to coach. At this minute, have them look at their sights and/or scope and see if they are still on target. Then you can address proper breathing, jerking vs squeezing, and follow through as Andy stated.
Also, even if someone started off with .22's and became proficient with them, they sometimes will still form a complex when they get around "LOUD" guns. I'll give an example here. When my oldest daughter was 9 (the age that she could demonstrate proper gun handling and safety to me), we started off by me drawing pictures of what proper site pictures (iron and scope) should look like (leveled/crosshair alignment) on paper. She then became a very good shot with a .22. Later that Summer, she wanted to try the "Big" gun (.243). So, when that time came, I fired off a couple of rounds to assure the scope was on. I then asked if she was ready......and she said NO. I said, "I thought you wanted to do this, so you can deer hunt this year". She said "Uugh, (and with eyes as big as saucers) I've got to go to the bathroom daddy". "Okay", I said. While she was gone, I was scratching my head trying to figure out what was wrong. Then it hit me, when I fired off the 2 rounds, she had been standing off to my side. Even with ear plugs in, the sound is still very loud compared to a .22. When she came back, I didn't mention this. I just told her that I wanted to shoot another round for accuracy's sake......and if she would, please stand directly BEHIND me. She did. After firing the round, I turned around and said "See, it's not nearly as loud standing behind it is it baby?" She smiled and said "No it ain't daddy". I asked her if she was ready....she said YES! Once the first round was fired, there was no turning back. We started going through the same motions as if it was a .22, along with positive re-enforcement after every shot, and all was well very quickly.
I truly think that the louder sound of larger caliber rifles has a negative effect on new shooters (old and young alike). Somehow, they associate the BOOM with dramatically increased recoil.
Sorry about the long post. Thought maybe it might help.
