The other weekend my uncle and I were out patterning our shotguns. He pulled out his chronograph just to play around with it. My Kent fasteel patterned great and the speed was right around their advertised 1560 fps. When it came to my uncle who was using Remington Sportsman Hi-Speed Steel his patterned decent but only flew at average of 1250 fps. No where near their advertised 1550 fps. Has anyone else had this with any other ammo? I actually never thought to check the speed but after this im going to be alittle more skeptical about new items claiming hi velocity. Maybe I'll just stick to my Kent Fasteel.
