Hey, PCP air gun enthusiast here. Hi air guns are as follows: AEA Zeuss 72 Cal, Air Force Texans with updated valve 45 Cal, AEA terminator 357 Cal, Air arms LCS- 19,25 Cal full auto, Hatson Blitz 30cal Full Auto, and a few others. I do a lot of velocity and FPE testing, and will post info on this on this site. These guns are quite amazing. Some better than others though, as you shall see.
