Need to better understand
One thing that I can't really understand is what my 24J rifle (regulated) is doing.
Charged at 200bar it shoots at 304m/s and is spot on the target, and I do mean spot on, 5 shots or more, in the same hole.
Somewhere after 10 shots it starts to open up, but still continues to shoot strongly at 304m/s. At this stage the pressure indicator has dropped to around 180bar (approximately as the scale is far from being easy to read).
Continuing to shoot, meaning more 30~40 shots (pressure around 100bar) it will never can regroup as before, but, and here's the puzzle, it continues to shoot at 304m/s.
Charged again to the max 200bar, et voila, the super tight group comes again, but only for 10 more shots... after that it spreads again.
Any light on this?
depending on skirt of the pellet or whole pellet perhaps what you are experiencing is a failure to upset into the rifling at the lower pressures. have you ever tried various head diameter pellets to see if there is a change.

Yes indeed, with 4.50 - 4.51 - 4.52
I'll try when weather allow with a heavier pellet to decrease velocity.
