I did wonder that, but the breech only gets an occasional wipe with Parker-Hale Express Gun Oil.

Tony, 27 years that's amazing The broken seals in the pic did look OK and worked I only decided to change them because the fps was inconsistent, I wonder if you tried to remove your old ones they would crumble, I have now fitted a new standard seal and the fps are consistent, but I'm thinking of getting a heavy-duty seal from somewhere if they are easy to get, I have had almost indestructible Diana breech seals from Terry Robb but not HW.
