Ballistic calculators and unregulated guns

[Beanflip]

Are Ballistic calculators worth using for unregulated airguns? They must be less effective with them than with regulated guns. ?

A properly tuned unregulated PCP should hold the velocity within a 4% ES.... That will cause an unnoticable POI shift for the average shooter at 50 yards.... If you are shooting at 100 yards, tune it to hold a 2% ES, same thing.... A good regulated PCP will hold a 1% ES....
