I've never figured out why I would want the target to disappear from view at or near the moment of the shot. Difficult to 'keep your eye on target' if the gun demands the target be covered with the muzzle.

Incoming shots excepted, I like to see the target when I shoot - thus the preference for a high shooting gun.

I sold off two very nice 20ga SxS guns simply because they required a technique which I don't enjoy.

Wobble trap is a good trainer for shooting targets that are not rapidly rising, and the game can be played with a standard trap gun just fine if you simply keep the bird in view. Ditto falling targets on the SC course, or decoying ducks. Just remember that if you don't see the bird, you will likely overshoot.

No big mystery to this... except the continued assertion by some that they 'never see' the sights or gun barrel. Shooting any gun without reference to some kind of front sight is impossible.
