PRC bullet seating depth

[blackfoot95]

I'm getting ready to work up a load for a 7mm PRC. normally I'd measure the distance to lands and adjust accordingly but being that the PRC cartridges are designed to have extremely precise chambers I'm considering just using the C.O.A.L. given by the manual. What have ya'll been doing?

there's nothing more precise about that chamber than any other chamber.
I load a bullet in a case with a bit of lube on it and slam it into the rifling which pushes the bullet back into the case. I take .030" off this measurement and compare it to the max length my magazine can take then I load to which ever length is shorter and go from there.

I would see what my chamber says. Then you know for certain.
