Here's a graphic that shows the trajectory effects of velocity. The pellets are all JSB Exacts. For anyone using a sub-500 FPS gun it's obvious why the far targets are so tough to hit. The AR20FT is a hair below the 12 ft-lb limit at 797 FPS but has a higher scope mount.

And of course there's the longer flight time with the slow pellets giving the wind more time to push them laterally, which requires about 50% more windage compensation. For someone to hit half the targets with a sub-500 FPS rifles is a real accomplishment.

When we were forced to shoot with sub 500fps guns for part of the 2010 season, we cut the maximum distance down to 35 yards which got us close to what a 12 ft/lb gun was like at 55 yards. You better hope for a real calm day to shoot sub 500 out to 55 yards.
