At 1150 fps it is fast enough to get the job done. Theses shells have brought a couple of old 10 ga out of the closet. Shooting some clay pigeons worked great, pattern great on paper. I only shot 4 shot s for the pattern test, the rest have been some clay pigeons and hunting. The birds fell over just as dead with theses shells at 1150 fps as the do with the modern hot loads, but my shoulder enjoys these shell. Would recommend and will be buying more. Thanks for the good work RTS
