Ok, I have been sitting back eating popcorn and reading all the posts and have to comments:
1. As to the major/minor argument. USPSA is a game and it has certain rules. Just like baseball and hockey. We can lobby for rule changes but it is what it is.
2. All this discussion about ammo performance. Why yes there is ways to scientifically tests different rounds that only goes so far. My job puts me in a position to see many people who have been shot and actually been in shootings. What I have learned from 13 years is shot placement is the key. Just had a bad-guy get shot by the good guys 4 times with Speer Gold Dot 200gr +P .45. Twice in the gut, once in the shoulder and once in the elbow and the bad guy lived. I have also had a bad guy drop dead with one Speer 9mm 124gr +P round. I have also seen plenty of individuals die from ball 9mm, .40 and .45 rounds.
Sooooo basically, the rules are the rules now in USPSA. I shoot my local matches with a Glock 19 in Limited and usually finished first in Limited. Also comes down to practice. I shoot minor in limited when i do because it is cheaper.....but I mostly shoot three gun where there is no power factory.
