Shooterill..Poor choice of words. Bite your tongue, HARD They may be physically challenged but they are not handicapped. Just ask any one of them. And they usually rise to the challenge without complaint.
Shooterill............my son is in a wheelchair. Your attempt at humor doesn't strike me as funny.
Honest answer is the shooter with the sporting clays gun (Browning) will be handicapped more at trap that the XT trap shooter shooting at sporting clays.
REason: trap target is rising and the sporting gun will require you to "cover" the target, lose full sight of it, to hit the target. The trap gun has some built in lead (shoots high) and therefore you don't lose sight of the target while breaking it.
Furthermore, the adjustable comb on the XT trap may be lowered thus lowering your point of impact if you wish for sporting targets OR more importantly to get the gun to shoot where you look.
I have shot the left hand XT in another post that I have for sale at sporting clays as well as trap. I don't shoot a lot of sporting but went to two or three shoots last year. I shot against many of the best in the state and finished right near the top (2nd), (first), top 6 or 7, with that XT trap. I was not handicapped because it shoots where I am looking.
The sporting guys still believe you need a flat shooter. You need a gun that shoots where you look and fits you. Krieghoff, Perazzi, Guerinni, Blazer have all come out with guns for sporting with a bit higher rib to adjust that point of impact, and these are sporting guns.
The ribs on these guns are similar in height to the XT trap.
