and a host of other things, like the base of the plastic pellet burning from the compressed air in the transfer port.... or some sort of venturi effect somewhere (although Condors have pretty much a straight through port).... However, when you consider that the 1647 fps value would require 100% transfer of molecular velocity to the pellet, any value approaching that would tend to raise one's eyebrows.... BTW, here is the calculator I used to get the 1647 fps for the RMS value at 20*C....

I don't have a horse in this race.... although I must admit I thought the "limit" made perfect sense.... I started the thread at the CAF out of interest because the "1650 limit" was posted on yet another Forum.... and somebody at the CAF with a Condor took up the challenge.... Now I'm not so sure.... Theories are only valid until disproven (not saying that is the case with certainty).... and then it's time to find a new theory to go with the facts, if necessary....
When you consider what happens to the BC of waisted (diablo) pellets in the Transonic region (over Mach 0.8-0.85, 900-950 fps) where it drops like a stone.... I don't really care anyway.... If anything I shoot approaches 1000 fps, I look for a heavier pellet....
