Fx panthera

Set the macro at 1 and leave it there. Reg at 130. Set micro to 1.5. Load and shoot pellets, check speed. Increase micro 5 clicks at a time and recheck. Use finer increments to arrive at micro setting that shoots the pellets at the speed you want. At that point leave the micro where it is and note that Macro 1 will be the setting for your pellets. Then load the slugs and find their desired speed by increasing only the macro (which works by jogging the micro in a reversible manner by 5 clicks or so). Note the macro setting that works for your slugs and you’re done. You just switch between the two macro settings whenever you change ammo and leave the micro alone.
 
Mine shoots the 33 Gr Zans lights out. Reg is set to about 160. Macro is at 22. Micro 3.5. Fps on the LabRadar is about 1060. Gets about 18 shots on 250 fill before dropping off of reg.
Tried it out today. Reg at 130. Macro at 1. Micro at 1.3 fires the 16gr pellets at 850 fps. Couldn't quite get the speed up for the 33 gr zans but I set the reg to160. Macro at 13 and micro at 3. Speed was 1020 fps very happy with grouping. Thanks again guys for the advice
