When the Browning XT first came out around 1996 it became more popular for sporting clays than trap.
I shot one for sporting clays for six years until I switched to a Beretta auto. The 30" is the perfect barrel length because Browning barrels are heavy and the 32" makes the gun nose heavy. The gun will shoot about 60/40 which is perfect for sporting clays.
If you look at the current Krieghoff, Kolar, Blaser, etc. sporting clays guns you will see the straighter stocks-some Monte Carlo-and taller ribs, all similar to the Browning XT.
