Trap is normally shot with 12 ga. and a full choke. Just for self-punishment, I shoot it with a 28 ga. and so try to shoot earlier and with a bit more open choke. I shot 12 ga. trap for years some time ago and finally got bored with it. With the 28 I don't get bored, but on the other hand I don't hit a lot of the targets right now.That's a pretty good study of trap. Another thing an ex-navy pilot advised me, he is a great trap/skeet shooter, is don't wait too long getting the target sighted and firing. You might be out of range real quickly if you wait too long. the type choke you're using could effect that range.
