Here is a video review I did on one of my refurbished Umarex APX rifles. I picked the rifle that gave me the highest velocities during Chronograph testing. I didn't video any of the Chronograph work so it isn't included.
The highest fps I could get was around 600 using Gamo PBA Raprtor 5.4gr pellets. fps with "the one", Crosman Wadcutter 7.4gr, averaged about 555 yielding about 5fpe.
