New CPHP 177 warning

[Florida_Man]

I was testing a rifle with a chronograph and tried these pellets since they are cheap. I got some crazy numbers. I then verified with my M853 and it happened with that rifle. I’m not buying any more of these Brazilian CPHP’s in 177.

I did a brief test with the 22 CPHP and they performed fine

I've always had wild readings with CPs but we're talking a 40fps spread at most. That is insane

My M853 is very consistent, it shot most around 430 fps. One literally came out at 102 fps. It bounce of the cardboard 8 inches from the muzzle.

Interesting, thanks for sharing

Just wondering how much under size a pellet would have to be to lose almost 500 ft per second.

I shoot them on occasion and haven't had as large of a fps swings as yours . They always have more STD than other quality pellets . These are the crossman cphp 7.9gr . Using a Taipan short.
