Ok, here it is my Chrony tests starting with my B-4-2 that has
over 3,000 shots on her.
B-4-2 .177 cal. Slick 50 treated only, using Crosman pointed pellets.
After doing the restoring process treatment.
B-4-2 .22 cal. with the restoring process, using crosman domed pellets.
This test is with a B-21, .177 cal. with the restoring process treatment, using Crosman pointed pellets.
Here is another test with the QB 36-1,.117 cal. with "Slick 50" and crosman pointed pellets.
This time I tried a XS B-3 Ak style .22 cal., with before and after the treatment using Crosman domed pellets.
After the restoring process.
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.
