Hiya DVD.
I've thought along same lines as you as regards the sled and bearing but was unsure if I was seeing something others couldn't. That is to say that if you tighten the sled up by increasing downward force on the bearing it will simply bite harder on the metal to maintain its position. Whereas less pressure would be needed for it to sit correctly aligned in the recess? That's my take anyhow? Surely one is the same as the other? But one method (the way the manufacturer intended) means less wear? I'm happy to be corrected! Interesting to rear your observation on negligible wear on the mechanism by the way. And I totally agree, if by adjusting the sled you end up with a 48/52 esq action then simply buy a 48/52 as they are lighter! As I said earlier I've not had any issues with shooting thee gun below or above the horizon. Certainly I shot a grey earlier this year at literally vertical and it connected no issues and lights out.
HW55T, I hear what you're saying and it's a shame there isn't more choice of semi recoiling guns. I can't vouch for both AA and FWB but owning other guns from their range Incan well imagine that the guns you mentioned are fine weapons. From my experience here and now I'd stick with the Airking but would happily try out others.

I think you are on the right track Dave. The ball is meant to nearly drop through the slightly smaller corresponding hole in the action so that it provides just the right amount of resistance as it climbs out when the action recoils. Now if the ball does not fall as much as it was designed to because it is being prevented by any added washers restricting the movement of the sled mechanism, it means that there is less resistance for it to climb out of the hole resulting with an action that flies backwards more readily and hitting the end stop more forcefully.

Try and visualize the breech ball detents that Diana uses on some of its airguns. It only takes a breech washer that is a fraction of a millimetre too thick to prevent proper seating of the ball over its detent and for the barrel to break open with a just a slight tap on the foresight.

The same applies to an incorrectly engaged ball on the 54, so people erroneously increase the pressure on it via the screw and spring just to hold its partially engaged position with the action forward. When the gun is shot and it recoils, the ball readily slips out of its hole because its nearly out anyway, but now the added pressure on the ball is going to exert more pressure along the path it slides in, which increases wear in that area.

Standard is best I reckon. Diana knew what they were doing in this area and its not called the Airking for nothing
