Went with a couple ball powders to make most use of 308 case volume.

Just did one round of each load for velocity/pressure indications.

I'm going to load up some of the 51/52 gr 2230C for an accuracy check. Curious how they will do jumping .150" to the lands. Only one way to find out.

QL calc's for 2230C. I factored up the case volume from 58.0gr to 59.0gr to account for the freebore. Calcs and velocity are fairly close. 53gr at 3200+ looks nice, and the brass or bolt lift didn't show any issues, but at 67K calc'd pressure, it seems prudent to back off to 51-52 grains.

Powder indicates AA2460, as indicated by AA, as 2230C is not a standard powder.
