After posting for help regarding the fitting of an external lanes regulator I had help off a fellow air rifle owner who showed me how it was done. Yesterday after what seemed an age I finally got the rifle shooting at a decent ft/lb with 10 gn pellets and 10.5gn.
I filled the cylinder to just under 200 as the 300 bar bottle I'm using needs refilling.
What would you recommend filling the cylinder to now the regulator is fitted?
Below are the results I had with 3 different pellets and all fired through a chrombro 4 chrono.
What are your thoughts regarding shot count as the regulator is set at 105bar by lanes and I haven't altered it. Would lowering the bar setting get me a higher shot count at the same fps?

For pellet weight I'm going by tin weight as I didn't weigh then this time.

Here's what I shot and ft/lb per different pellets.
10gn RWS Super heavy
67 shots
Highest fps 723, 11.61ft/lb
Lowest fps 715, 11.35 ft/lb.

10.5gn Crosman Magnum
67 shots
Highest fps 704, 11.56ft/lb
Lowest fps 698, 11.36ft/lb.

Daystate Kaiser 8.64gn.
Highest fps 765, 11.23ft/lb.
Lowest fps 754, 10.91ft/lb.

Only got 61 shots though with the lighter pellets probably because it's using more air to push them?
