NEW SEAL REPLACED IN THE DIANA

AOA gave me 2 seals one a little bit smaller, his thought was see what happens. My FPS dropped down to 630 from around 680. I did use the krytox grease. It is shooting OK out to 30yds, but I had the jerks today. It never got over a hundred today so not sure what is going to happen. I decided to take the moderator off to shot it. If things don't go well with this seal, I'll try the other one. Now that I've taken it a part, it is only about a 15 min job. The picture is about 30 shots at 15 yds. This evening. and a rabbit head shot at 35 yds.

Looking better but I imagine the real test will be during the greater temperature swings.

Since they sent you two then I would try them both just to compare and stick with the one that performs most consistantly and reliably.



When you had it apart did you check the spring chamber for any burrs that could damage the new seals as the piston is inserted? I'm sure you dont want a repeat of what happened to tje original seal...
