Can some one explain the difference to me. Is it the speed of the bullet?
Im trying to figure out what my rounds are for a match app. Im assuming factory 9mm would be minor. |

Quoted:
all 9mm outside of open will be scored minor even if it makes +165 power factor. Anything below 125 your shooting for fun. That is a very important fact. There is also production division where everything is scored minor regardless of whether it makes major power factor or not. |

I am looking at 9x23 Win is the reason I ask. 9mm as in bore size. 9x 23 would be minor and a bad choice for major only due to brass cost, 38 super and 9x19 can be loaded to major pf for open. revo, forgot about that class. |

revo, forgot about that class. DIVISION. You of all people should know better. Here's a rundown of the current USPSA divisions: Open - 125PF for minor, no other restrictions. 165PF for major, and the bullet must be at least 112gr. Limited - 125PF for minor, no other restrictions. 165PF for major, and the bullet must be at least 0.400" in diameter. Limited 10 - 125PF for minor, no other restrictions. 165PF for major, and the bullet must be at least 0.400" in diameter. Production - 125PF for minor, no other restrictions. Major power factor is not recognized. Single-Stack - 125PF for minor, no other restrictions. 165PF for major, and the bullet must be at least 0.400" in diameter. Revolver - 125PF for minor, no other restrictions. 165PF for major, no other restrictions. All divisions have a minimum bullet diameter of 0.354" and minimum case length of 0.748". And the IPSC divisions: Open - 125PF for minor, no other restrictions. 160PF for major, and the bullet must be at least 120gr. Modified - 125PF for minor, no other restrictions. 170PF for major, and the bullet must be at least 0.400" in diameter. Standard - 125PF for minor, no other restrictions. 170PF for major, and the bullet must be at least 0.400" in diameter - EXCEPT that .357SIG is explicitly recognized for major, if it meets 170PF. Production - 125PF for minor, no other restrictions. Major power factor is not recognized. Revolver Standard - 125PF for minor, no other restrictions. 170PF for major, no other restrictions. All divisions have a minimum bullet diameter of 0.354" and minimum case length of 0.748". |

Would factory 40 S&W ammo make Major? Yes. Most factory 180gr is usually 175~180 PF. Factory 155gr and 165gr should make it as well; IIRC, some of those loads are even hotter. ETA - But before going to a big match, you should still check with a chrono, doubly so if you run a gun with a shorter barrel than most, since you will be losing velocity compared to longer barrels. |
