New guy here. Thank you for adding me. Question for the group. I have an older Gamo 220 hunter that I got a long time ago. Close out from Cabelas. It’s always been crazy accurate right up until I replaced the breech seal. Now the gun doesn’t seem to lock up consistent and strings shots up and down a target. Is there something I need to do after replacing that seal to get a good lockup ? TIA

Breech seal question

It may take some time for the new seal to develop some compression set. Meaning it may not be fully closing yet. If you still have the old seal, you might want to try reinstalling it and compare the resulting gap against the new one.
Is there any chance the new seal is the wrong size? Metric vs standard is one possible difference if you selected the replacement yourself.
Another possibility is the new seal simply isn’t sealing. Have you tried draping a piece of tissue over the breech when you fire? Does it get disturbed by a pulse of air?

I think you are correct. It is the correct seal but it hasn’t take a set or confirm to a uniform compression. I put the old seal back in and it’s back to its former glory. Much to the chagrin of some small pests.
