what's the difference between the 20PPC and the 20LBC?
The 20 PPC is the 6 PPC necked down. The 20 LBC is a 6.5 Grendel/264 LBC necked to 20. A bit more boiler room from use of the Grendel case. I am hoping for some very god velocities in use with the poly rifling that usually will see an up in the velocity levels by itself as you can pump them up a tad more thanks to less pressure on the bullet/barrel interface.
