There are numerous examples that bring this into question, head to head. UBR is the only short range format that I'm aware of that has a reasonably equal number of different chamberings. In it, there are also a pretty equal number of winning chamberings...head to head with PPC's. I'm not advocating anything. Just stating a fact, based on what I see in the only game with a fair number of different chamberings facing off, head to head, in the same conditions and at the same time. I really think THAT tells us all more than what wins in a game where virtually 100% are shooting a PPC. In that case, it's easy to guess what wins, just about every single time. Unless you regularly shoot against othee chamberings...in competition, head to head...I really have to think it's a stretch to matter of factly state that any cartridge is KING. Nothing more, nothing less.
