I don't know the brand, the shooters or teams arrange for their own ammo. John

"Cogdell follows the same airport procedure as Turner, with one exception. "We don't carry ammunition. We used to, but regulations changed, so we make arrangements to receive ammunition where we compete.""

"Olympic shotgun games use shells with speeds of 1300 fps and shot loads of no more than 24 grams, maximum allowed is 24.5 grams ( less than 7/8 ounce). The shot size is 7 ½ . This is a very fast load that delivers a high punch (kinetic energy = mass x speed) required to break the hard targets. Yes the targets are harder - more ribs – and also shallower. This configuration makes them tougher to break; reason why you need to shoot a load that delivers a good punch. The loads are 1,325 fps but do not be afraid, due to the light shot load the recoil is less compared to a 1250 fps 1 1/8 load used in AT Trap.
Targets are shot within a range of 55 meters. That is a bit more than 55 yards (1 yard is about 0.9 meters) or 167 feet. Most American Trap shooters break targets within 35 yards; big difference isn’t it?"
"The shotguns used for Olympic trap are 12 guage. Most of these guns are low rib and hence have low point of impact (POI). Most of the guns shoot 50:50, but some shooters also use guns with 60:40 PIO. In contrast, American Trap guns shoot very high points of impact. You may ask yourselves why is this? For one, the Olympic game has very hard angles (45 degrees) and it shoots targets at 65 mph (American Trap is 40-42 mph). Also the height the targets travel is not fixed, it varies from very shallow to very high (1-2 meters to up to 10 meters)."
