It sounds to me like you are stepping back and forth across that line where pressures are going up very fast with small increases in charge. Flat primers followed by pierced primers is a natural progression of pressure indication. You can hide the symptoms by going to a thicker cup but the pressure is still the same. If it was me doing the shooting and it was my gun I would back the load down a grain and a half below where the symptoms did not exist and call that the maximum load with that powder/ bullet combination in that rifle. You do what you think is right.

Good advice!
