I have a 257 Roberts red pad ultralight that is in great condition save for a bit of an issue. It doesn't fully eject fired brass (or unfired rounds for that matter) It extracts the round and lets go of it on top of the magazine follower. I also have a MK II ultralight 257 Roberts. It functions flawlessly. I ordered a brand new spring for the Red pad. It didn't help. I switched the follower from the MK II to the red pad. It didn't help. I switched bolts. The Red pad bolt works fine in the MK II. The MK II bolt has the same ejection issue in the Red pad rifle.

Any ideas? I am befuddled.
