BM, I'll go out to the shop and see if I have any of them left. Seems like there's a couple boxes out there, and I'll see which ones they are. They're 16 ga., I know that much. Bought them to shoot in my 32" barreled 16 LC Smith at the Fall Southern once. They were good enough that I qualified for, and competed on, the LC Smith team in the Smith/Parker challenge. I shot the whole round with nothing but spreaders as the gun is choked exceedingly tight on both barrels. They worked great on the targets we shot, but the ground was covered with confetti when I left.
It is my understanding that spreaders get an increased spread from higher velocity. Makes sense. The Interceptors not only are incredibly uniform in patterning, but they feel exactly like my 1150 fps 1 1/8 oz. competition loads. I like not being able to feel the difference when I trigger them.
Will report back on the RSTs in a while.
