Yes, compressed powder might be an issue but the bearing surface of the bullet is the primary factor affecting chamber pressure. The Barnes technician advised me that I should treat this bullet about the same as a 200 gr jacketed bullet, even though the 155 gr all copper is longer.
Just here for the 10mm death ray talk.
