FX probably set your Wildcat MKIII up perfectly from the factory. You don’t have to change anything and just shoot it as it is.
Now then. There are so many ways to do this but this is my way, and I am only sharing it because you asked me. I like to help people out.
@ whatever AMP regulator pressure you set your Wildcat on
(On power #7)
Quarter turns on the adjuster at a time (counter clockwise), then chronograph a few shots.
Is the speed increasing?
You want just enough hammer tension to reach the MKIII’s highest velocity with the AMP regulator’s pressure setting. No wasted air! Wasted air causes inaccuracies and poor efficiency.
Quarter turns are the moves you make then chronograph a couple shots, whether adjusting up or down. Find the top speed while power level # 7 is selected.
Now, here comes the efficiency part…
When and after you find the highest speed ( on power level # 7) Turn your HST wheel down to power level # 6. Take a few shots over the chronograph on power #6. You should see a 10 to 20 fps slower velocity. If you don’t, then you have got too much hammer spring tension. In other words you are adjusted too far out, which wastes air.
Dial it back… (clockwise) Quarter turns and take a few shots (Over the chrony) on power #7 and power #6. Until you see a 10 to 20 fps difference between power #6 and #7.
*BUT* You still want power # 7 to be at or around that highest velocity that you where reaching. But power #6 is a slower velocity. 5, 4, 3, 2, and 1 power levels should all gradually be slower and slower fps.
Make sense?
Look at my power levels 1 through 7. Using Air Arms 25.4 grain pellets?
View attachment 93422 Remember:
If there is no difference in speed of power 7 and 6 you’ve got too much hammer spring tension, and power 7 is wasting air. You want your highest setting to have just enough regulated air and hammer strike (tension) to the valve to give you your top speed. Nothing more nothing less. Every lower setting will fall where they fall, but gradually get slower down to power level #1.
