When I ordered my gun I asked what pellet most people liked for this gun I was told the JSB Exact 25.4 grain so I ordered one tin of those and the sampler pack from Straight Shooters with the gun. I decided to get out the chronograph and do some testing with my sampler pack. To start with I shot a string with the JSB Exact 25.4 Gr to get a base line I get 41 shots before the velocity starts dropping that is filling to 220 Bar. Groups at 30 Yds have been running from 1/4" to 1/2" average I think this could be better as I get used to this gun and make alterations for it to fit me better. I am shooting all of these test groups under the exact conditions very light to no wind outdoors.
Here is what that shot string looked like in columns of 8 you can see where the velocity starts dropping on the 42nd shot..

12) Benjamin Domed 27.5 Gr 873.6, 873.0, 872.5, 871.3, 871.4, 873.2, 865.3, 863.1 Group @ 30 yds 3"

14) H&N Baracuda 31.02 Gr 850.4, 850.4, 849.2 the magazine did not want to rotate they were too long the 3 shot group was about 3/4"
15) Beeman Kodiac Match 31.02 Gr too long for the gun.
This test is not exactly scientific but I was disappointed that some of the pellets obviously did not stabilize the overall target size was about 16" x 16" and several did not even consistently hit the target at all. I plan to do some more testing but I don't expect the outcome to change the JSB Exact 25.39 Gr shot way better but some of the heavy pellets showed promise. I am surprised 4 out of 15 of these pellets were too long for the gun. If the breach would have been made .050" wider all of these pellets would have fit. I can't believe FX did not make the breach wider or if this was a mistake in manufacturing.
Don't get me wrong I still like my gun but the safety could be better and the breach should except these longer pellets. I am guessing the pellets that did not stabilize where either under sized or something I plan to mic them all out in the future to try and figure out why they did not shoot. At one point I thought something was wrong with the gun and put the JSB Exact 25.39 Gr back in and it shot fine again.
