Yup and the bolt action loads they set max pressure on at 62000 PSI while it is 52000 osi for the AR, so there will be less velocity from an AR at those pressures

This is their gas gun data; bolt gun data shows a higher MV possible, and pressures up around 62K rather than the 52K for gas guns.

AR-15 data in the link above

3000 FPS for 75 grain in an 18” barrel

Looking at some other sites this data lines right up with 6mm PPC load data for velocity which makes little sense , I was hoping it would line up more with 6mmAR or 243 LBC velocities .........

3000 FPS isn’t terrible especially from an 18 inch barrel. I like my 243 at 3300fps better though, really don’t want to have to step down to the 50 grain bullets. That 75 Vmax just wrecks the coyotes

just saw george gardner ga precision is on the bandwagon, hes going to build a ar-15

and

a bolt action which will really make this an effective round.
