Yes, "dang" physics, like gravity it's always on.I found this on Airforce's web site. I would guess the data is based on the Texan fill pressure of 3000psi, which is kind of where I would want to regulate to when tethered and I think it just gives so apples to apples comparison on the same plateform from one caliber to the next with bullet weights...etcSourcehttps://www.airforceairguns.com/Articles.asp?ID=143#3
I'm wondering, given the discussion above - is there a "sweetspot" calibre for airguns?
