FX BobCat Air coming from the breach.

Yeh - I know others have posted about air coming from the breach of there air rifles and the first thing to do is replace the seal.

I did that and it I still get a puff or air when I shoot a pellet when the mag is removed.
It looks like the probe is inserting far enough. What else should I look for?

I don't have a bobcat, but had the same thing happen on a wildcat. Still had a puff of air after replacing the breach O-ring. Put a heavy layer of synthetic grease on the pellet probe and fired it and it blew the grease off so was definitely coming by the new O-ring. Replaced it again and all was fine. Maybe I scratched the new one putting it in, maybe a bad new o-ring, maybe the gods just didn't like that one. Who knows.
