Hoping this may help some of you anticipate until you get time to do your own testing, see below.

Within a perfectly controlled indoor environment with no wind, temperature about 65 degrees, I was able to test the following pellet/rifle combinations for trajectory, shooting 5 shot groups. Note, each of these combinations will shoot groups of .25 inches or less at 15 yards.

Air Arms S510 .177 Cal, charged to 200 MB/3000 PSI, +/- 1000 FPS shooting a JSB Exact 7.87 Grain Round Nose Pellet

10 yards = -.75

20 yards = -.25

30 yards = 0

35 yards = .75

50 yards = -1.75

60 yards = -2.25

------

Air Arms S510 .22 Cal, charged to 200 MB/3000 PSI @ +/- 900 FPS
Meisterkugeln Wadcutter 14.0 GR

10 yards = -.5

20 yards = -.25

30 yards = 0

40 yards = -.5

50 yards = -3.5

60 yards = -5.5

70 yards = -8.5

80 yards = -14.5

-----------

Diana RWS 54 Air King
Spring Piston/Side Lever Cock
+/- 600 FPS
Predator Polymag 16.0 GR Pellet

10 yards = -.5

20 yards = -.25

30 yards = 0

40 yards = -2

50 yards = -4.5

60 yards = -6.5

70 yards = -10

80 yards = -14.5

I believe the opportunity for solid groups existed. I just didn't do my part. Because of ground conditions and other situations, I did not have a good and solid rest. I was shooting from vertical position using a tripod to support the fore end. If I had been shooting from a bench where I could get solid support on the butt of the gun as well, I believe the groups would have been much better.

They held within +/- 1" out to 50 yards. Once I got to 80, the groups opened up to +/- 3" with the .22s, and +/- 2" with the .177.

Cool, cool. Not bad at all. I've surprised myself a few times with 70~ yard shots at doves in treetops that connected- never tried shooting groups at that yardage though
