hoss shoer Posted January 16, 2023 Share Posted January 16, 2023 Do bigger matches state/regional or national level WB matches set up a chrono stage like USPSA matches do? If so has anyone run one for a match? How was it run? Thanks in advance Hoss Shoer Quote Link to comment Share on other sites More sharing options...
Nickel City Dude Posted January 16, 2023 Share Posted January 16, 2023 I have never seen one set up at a Cowboy match. I suspect that the space, time and personal necessary to do this makes it unproductive and just a plain old PITA. Quote Link to comment Share on other sites More sharing options...
Flying W Ramrod Posted January 16, 2023 Share Posted January 16, 2023 Yep, they do. Nope, not everyone runs through. They pull names, at random, at the start of the match and those shooters have their ammo checked. At Cowboy matches, they chrono only those who sound/look like they're below power factor. Usually because of a challenge by another shooter in their category. Quote Link to comment Share on other sites More sharing options...
Garrison Joe Posted January 16, 2023 Share Posted January 16, 2023 (edited) One way I've seen chronographing done is for the selected shooters to be approached when at the loading table and asked to give up ten pistol rounds and same number of rifle rounds. Done at loading table so that loads the shooter actually uses are tested, not just "special box of ammo from the cart." Five rounds get shot over chrono from the match's selected firearms. If some unusual caliber rifle is being used, the competitor's rifle is used by match officials at a time which does not interrupt the stage. One round is pulled apart and bullet weight is obtained. Failures of the 5-shot average power factor (calculated from average velocity and actual weight of bullet) to make minimum power factor are retested. The shooter is given one more chance, providing their own firearms and the match officials will shoot the remaining collected ammo. Done because some competitor guns show higher velocities than the match test firearms might. Failure to make power factor even by one-tenth of a unit is a Match DQ from Scoring, with shooter allowed to finish match but not eligible for awards. Testing before match starts is encouraged. How this will ensure the shooter's actual match ammo is what is tested is not described, however. All this is covered pretty well in the Wild Bunch Range Operations / Match Directors Handbook, Appendix B. Match directors are allowed deviations from the full procedures written there, as long as testing is done consistently. good luck, GJ Edited January 16, 2023 by Garrison Joe 2 Quote Link to comment Share on other sites More sharing options...
C.N. Double Posted January 16, 2023 Share Posted January 16, 2023 The guidelines for chrono testing are on page 23 of the RO/MD handbook. Edit: Since there is mixed information in this thread, here is an excerpt directly from the MD/RO handbook (but, I don't think anyone should "weight" your bullet after it's pulled 😬) : "One round will have the bullet pulled and weighted. Then, the remainingfour rounds will be fired over the chronograph. The average velocity of thethree fastest recorded rounds will be used to calculate power factor."

Jorge Posted January 18, 2023 Share Posted January 18, 2023 I have never seen a Chrono at a Cowboy action Match either. The Chrono has been used at most State and Above Wild Bunch Action Shooting Matches that I have attended. Procedures are outlined in the handbook. Pays to have a Chronograph to check your loads before attending a Big Match! Quote Link to comment Share on other sites More sharing options...
