My younger son became a bird-crusher by the time he was 10. (Ran his first 25, went 49/50 in his first competition. Punk)
First - how big and strong is your son?
Second - is he "ready" shoot a round (or more) of Trap? By that I mean have the stamina and focus to do a round?
My kid started at ~7, with a 20 ga semi-auto with a cut-down buttstock. By the time he was 9, he'd graduated to a full-size 12 ga semi-auto. But, he was a big, strong kid.
Not sure where you are, but if you're in the Metrowest area, I'd be happy to help you. My Club has some Junior-sized 20s, that he could try.
A 20 will give you 20% fewer pellets, which will result in lower scores, so he should understand that a 20 will handicap him.
I'd do this with pretty much all new shooters, and all new kids: I lock the trap on straight-aways from station 3, and have them break a few. Then, with the trap still locked, I have them take a few from other stations. I go through a box. Then, I ask them how they're doing. If they're getting beaten up, it will make it a misery. If you're not used to it, it's tiring and can be uncomfortable.
If they're still game, I unlock the trap, and have them shoot a round, starting on station 3, ALONE. This way, they can take their time, and not worry about inconveniencing anyone, or being low gun.
I find it counter-productive to throw a new shooter into a regular round. No matter how understanding and patient the other shooters are, the new shooter will have additional pressure to "keep up" which will not help.
So - biggest gun they can handle. Regardless of gauge, use a semi-auto. Individual instruction, preferably from someone that has done it before. Keep it mellow. Safe, but mellow.
Someone thought I should chime in.....
