We also Chronyed my cousin's Gamo Hunter 220, it averaged about 840 fps, although it is advertised at 1,000 fps. So as we can see, Chinese air guns are not the only air guns that have over rated fps on their advertisements.
And in case some of you are wondering, no, none of the air guns exploded in my face or broke down. There were 2 super sonic shots from the B-21 when the pellets broke the sound barrier (1,080fps), nothing else, all my air guns are working fine.
Sincerely,
Eddie
