Hi All, last week I tested the gun with the air pressure starting at about 190 bar pellets = Crosman ultra magnum 10.5gr and got 10.91, 10.98, 10,82, 11.72, 11.86. today with the same pellets, air pressure about 195 bar I got 9.11, 9.38, 9.49, 9.39, 9.49, 9.66, 9.61, 9.69, 9.84, 9.93, 10.03, 10.04, 10.13, it seems as the air pressure reduces the muzzle energy increases, but that can't be right or is it because the barrel warms up a little.
I am using a Combro CB-625 Mk4 about a couple of weeks old, could it be the Combro is faulty considering the difference from last week to this week.
