NOW USE ONE TANK FOR .177, 22 & .25 CAL ON AIRFORCE AIRGUNS

[pramodsid]

Finally you can use one tank for .177, 22 and .25 cal on Airforce airguns platform.

Am not sure this has been achieved before, if it has then the subject would have less emphasis.
Don't charge upon me for that !!!

The goal was to prepare a rig where you would not have to swap parts as that becomes cumbersome in the field .
Have been testing this out for a while and looks like the results are promising.

No more Tank Dumps.
Even tried the 90gr hammer on this rig at max power wheel to test tank dumps with the .177, there were none.

With 90gr hammer heavier hammer the .177 were travelling way above the supersonic speeds. Even the eun jins would.

Let the results speak for itself.

Would have loved to run a Shot String with .22 cal but didn't have a barrel to perform the test.

I could tune the rig further to get a lower Spread, but we ought to bear in mind, the versatility of using it across calibers without compromising on power and shot count.

Dedicated tanks could be tuned to shoot 50+ shots with an average spread lesser than 20. Do note it's a non regulated setup. With the regulated setup the spread could be least or minimum, but that would raise the cost of the setup too.

I have listed the entire bell curve, if you want to have tighter groups you could choose what best suits from the bell curve and fill to appropriate pressures to achieve promising results.

For those folks who are hungry for power, PCP Tunes heavier hammer or Extra Heavy will give you outstanding results.

Happy Safe Shooting !!!
