Texan 308.Lapped barrel, nearly no mods to the internals. Running a mounted 1100cc regulated tank at 2500psi. I get 40+ shots at 260fpe. Here are a few pics. I've been testing ammo and fine tuning the gun at distance. I have a picture of the rifle benched on my 230y range area. And the group I shot was 15 shots without really making sure the tank was perfect on pressure. Second picture of group I found out I needed to ensure the pressure was really precise (even though I have the hammer spring tuned to the bell curve around my reg setpoint). This was at 310y. Had to add 62moa of elevation in the scope. Does it look like it's shooting okay?!
