I have a BUNCH of .308 load data. Maybe getting started with this will motivate me to compile it.

Lets start with . . .

49.0 Varget
130gr barrier bullet (look at the 300 BLK thread for a description)
Winchester Large Rifle Primer (WLRP)
2.697 C.O.A.L.
Tight crimp (Lee factory crimp die)

I have not had the opportunity yet to chronograph this load. But based on my cyphering it should be running in the neighborhood of 3600-3700FPS. It does not show overpressure in once fired nickel brass.

As always: You are just plain insane if you use my data without starting well below it and working up from there in small increments.
