Hoot, Sorry to hear of bad outing to the range with the 275 XPB bullets. I was looking forward to you helping me come up with a starting load for my RAR.

Velocities are so erratic, by bottleneck caliber standards, that the impact of the primer variations would be lost in the "background noise". If there's any chance of comparing the results in this caliber, it would no doubt come from a cannelured or grooved bullet with a well regulated stab crimp, shot from a bolt action. (Yo Bob...) ...
