I would reccomend that you find out if your trap club has an instructor, or any memebers who are instructors.
Have them watch her and give pointers. Most complete novices willing to pick up the gun (including myself since I only started trap last year myself, everything before was rifle and pistol,) can break 3 or 4 clays by just dumb luck thier first time. I think she has multiple things working against her if she consistently hits zero.
I'd try not to give up on the trap shooting with her as it's the only shooting sport where I personally see women (albeit still in t he minority) who are consistently there to shoot. The socialization of the club, and the slightly more effete "european" connotations that the shotgun sports have helps keep women involved IMO.
It could be any number of things with trap:
- Her stance. Feet placment, trigger arm elbow not held high, poor cheek weld, and eye not over the rib etc. Bending to aim with arms instead of staying "locked up" on top and bending to aim with the waist only.
- Poor gun fit, to the point of being painful for her. Gun fit is critical for accuracy since you don't really use sights, and the only thing promoting repeatable accuracy is your ability to mount the gun in a consistent manner with your eye over the rib. Or perhaps the gun is simply too heavy for her, making it too slow to point.
- Perhaps she's trying to aim like a rifle, instead of watching the clay pigeon, and letting herself just naturally follow with the gun.
- Shooting with both eyes open which confuses her aim, or vice-versa, only one eye open which causes a loss of depth perception, each shooter is different on which is better for them.
- Eye vs. hand cross-dominance problems.
- Not understanding lead for sideways flyers and over shooting straight away clays.
- Flinching.
It's probably a combination of more than one problem for her shooting experience to be soo poor, and an instructor can help with eye-dominance, stance, and any gross problems with gun fit for her. If a few basic things that aren't "her fault" are fixed, and she suddenly starts breaking clays, her self-esteem and enjoyment will improve immediately.
