Okay, I understand what you're trying to say now.
I don't believe the high power failure is because the air starts to go past the BB. I believe it's because the rifling grooves are only optimized for a certain power rating. If the twist was stretched out or tightened up (I'm not too sure on the physics behind rifling), then it may be better optimized for high powered guns.
Japan has rules that restrict guns from shooting beyond a certain power rating, which is why Tanio Kobayashi skipped the idea of optimizing for higher power.
In fact, just last night, the manager of the First Factory store in Japan, along with five others in the shop were arrested for illegally owning and modifying airsoft guns to limits which could "cause harm or death."
