S200 screw size

[Smudgerii]

Can anyone confirm the size of the screw required for the TP adjuster? I will be attempting to remove the AT later and need to source the relevant screw and nut.

I have an S200, I`d no idea it HAD a `TP`!!
what`s a TP?
how do you adjust it?
why would you want to?
Help!

"What" - transfer port adjuster ( grub screw on left side of action, once I remove AT )
"How" - you use an allen key and turn it clockwise or anticlockwise dependent on desired result
"Why" - because I got sold it as full power when in fact it is set at 7ftlb with all AT fitted, so therefore it is a target action.

Once I have had the AT removed I will be able to use the hammer adjustment for coarse adjustment, and the TP for fine tuning to 10.7ftlb which is my preferred level for our shooting discipline.

Sadly the forum seems devoid of help right now, which is probably a reflection of the subject and peoples perceptions that I will be chasing illegal power.

The usual gunsmith I use is not available at present, and I intended giving this as a present on Friday, he will still get it but it will be no use on a 75yd range

The TP screw size is 3mm x 12mm long grubscrew.
You will also need a 3mm nut to lock it off.
