First off I recommend switching to Strelok pro. The chairgun is a free program and it behaves like one. If you really want top performance you need to use a pay ballistic program. Secondly, there are so many variables that could be the problem. Everything from mis-measured scope height all the way to the wrong magnification setting on your program. You also need to understand the BC is not a constant, it is an average. Those BCs found on chairgun may not be correct for your gun. They were figured on an average found in most guns, if you speed the pellet up you need to change the BC. Before you change the BC tell us your scope combo and if it’s a MOA or MRAD, and let’s start eliminating variables

I’d just shoot and remember, if you can’t do that then write it down on paper or your notes on your phone/tablet.
Most ballistic apps leave much to be desired, even the ones that cost some coin.
