Today my eyes were opened up so to speak when sighting in the AEA 357 rated at 340 fpe, at least mine is with 214gr but, at 150gr-3200psi this is max psi any more you start to lose fps,956 and 304 fpe. When you match that against my Texan .308 with 150gr 3300 psi 965fps = 310 fpe and max fpe 362.94 @ 3400 psi and adjust power wheel. both have heavy hammer springs. Still needs tweaking, was running out of day light. 5 shots from 100 yards 2 of them are from sighting in , 3 from what I have to tighten up. I was reloading with single shot tray.
