4. Yes Dear, We Intended It To Be A 9mm Division!
Why? The single biggest problem facing IPSC competitors attending Major Matches today (and in the future), is the carriage of ammunition on board commercial passenger aircraft. Now if we had Major and Minor scoring, it's clear from the other Divisions that the vast majority of people would chose to shoot Major calibre rounds for the higher points available for peripheral hits on paper targets, but they'd be caught in the same "custom-made" ammo recipe trap.
One definition of "insanity" is "doing the same thing over and over again, and expecting a different outcome"! By only offering Minor scoring, competitors would be able to use generic factory ammo and easily achieve Minor, rather than having to rely on home brews to make Major!
The idea was that if you had a problem getting your double-the-IATA-5kg-limit of 600 rounds of (whatever) factory brand of 9mm on board your flight to World Shoot, you can buy factory ammo at your destination, and your gun will work just fine and dandy. In other words, rather than perpetuating a known problem of shipping "custom-made" ammo, we found a solution, and all is well in Camelot and the birds are singing .......
