USPSA Handgun Competition Rules January 2008

. Specifically, power factors generated by a chronograph which indicate
exactly 125.0 or 165.0 shall be subject to confirmation since these values
could be the result of the “rounding up” of digits after the first decimal
place.
41. If a competitor’s match ammunition is retested, or if any authorized replacement
ammunition is used, and different power factors are recorded when
tested according to these rules, the lower power factor must be applied to all
courses of fire, including those already completed by the competitor.
42. The scores of a competitor who, for any reason, fails to present his firearm
for testing at the designated time and location and/or who fails to provide
sample rounds for testing whenever requested by a Match Official will be
removed from the match results.
Chronograph Station Rules and Policies
43. The Chronograph Station is considered an official stage in the match and
subject to all sections of this rule book.
44. The Chrono Officer is the CRO for the chronograph stage and issues range
commands appropriate to the requirements of the Chrono Station.
45. Shooters are prohibited from handling their handgun except as specifically
required to do so by the Chrono Officer.
46. Unless otherwise authorized by the Chrono Officer, once the handgun is
surrendered for testing, it may not be removed from the Chrono Station until
the testing is complete.
47. The Chrono Officer will inspect the competitor’s handgun and report any
failure of the following to the Range Master:
a. Proper function of the handgun’s primary safety mechanism(s)
b. Safe condition and operation
c. Compliance with the requirements of the declared Division
48. At the command of the Chrono Officer, the competitor may be required to
fire up to six rounds into a designated target or spot on the berm/backstop
prior to the competitor’s ammunition sample being tested through the
chronograph.
49. The Chrono Officer will perform the competitor ammunition testing procedure
as specified above and enter the results on a scoresheet suitable for
such use.
50. Following testing, should the interim chronograph results be close to the
minimum applicable Power Factor floor, it is recommended that any
remaining rounds of the competitor’s sample ammunition be secured and
retained at the Chrono Station for potential later reference or additional testing.
