I will plead ignorance as far as understanding why, I'm simply stating what was stated by someone who has already done conversions using these two particular cartriges. The 300 doesn't open, the 375 does. Maybe it's just an anomaly with that one action, who knows. Just saying it did happen so I wouldn't be stuffing my face in there first time it's fired.
