You asked the same question on another forum. Here is the answer I got for you from the designer of the Titan Manitou. Perhaps you hadnt seen it
I spoke to John Bowkett who designed the Titan Manitou range of pcps. When the rifle actions were assembled and tested the ones that were more consistent or gave more shots were put in a seperate rack for final assembly as Target versions of the Manitou. They had brass hardware and were fitted as standard with the match trigger. JB altered the leverage inside the trigger box and added one long horizontal spring for the match verson. It was offered as an option for the other models in the Manitou range and when set up is really a very light trigger.
The first thing to do is to remove "creep" by adjusting the sear engagement down to the lowest safe level. This is done using the rear screw and locknut. Once done and the loocknut tightened cock the hammer and bump the rear of the action with the heel of the hand to make sure the trigger has a safe level of engagement.
Final stage is to adjust the front trigger box screw to shorten the first movement of the trigger to suit your taste.
Wobble on the trigger can be removed by drilling and reaming insitu the front trigger pivot to take a 4mm x12 mm long precision dowel. This removes any play. Using shims just disguises the play. Your choice. Hope this info from JB has helped. Much more info and photos on the Facebook John Bowkett official fanpage
