New Long Range Rig...not a Grendel though
#14
If you use slower-burning powders and keep your chamber pressure low, you can have substantial velocity and excellent barrel life.

That is what George Gardner does with the 6.5 SAUM 4S. Keep chamber pressure below 58,000psi, preferably 55,000psi using large kernel extruded powder, pushing the 130gr VLD.
