Your ammo is fine is will be tested under the chrono process
Official Match Ammunition follows C3, which has always been in place but was recently updated to include commercial source ammo, specifically the 3 Federal Syntech Action Pistol.
For Nationals there are the following sources for Match Ammo
-Federal Syntech Action Pistol 150gr 9mm, 40s&w 205gr and 45acp 220gr (just these specific calibers and bullet weights)
Federal Syntech can be brought to the range (or shipped by you)
Precision Delta, Atlanta Arms and T1 have to be shipped by the manufacturer to the range
(the difference is that Federal does not sell directly to the public and can only be purchased from retailers)
At Registration if you are using the Syntech or ammo you had shipped from Precision, AA or T1 you must fill out a declaration form
At that point you will follow the process outlined in C3 of the Rulebook
-turn in 8 sample rounds
-go through chrono just like everyone else
-if your 8 rounds do not make it, then we pull and test the 8 sample rounds
(by the way this has not changed, it has been in place for many years)
Official Match Ammunition
Competitors using Official Match Ammunition are exempt from the requirements
of Appendix C2, Items 38 and 39 as appropriate for the declared power factor.
Source of ammo - Ammo must be delivered to the competitor only at the match
where it will be used and designated official by the US Regional Director.
Power Factor - Specific ammo products may be certified as meeting Minor or Major power factor for specific divisions by the US
Competitor Declaration -A competitor who wishes to use official match ammo at the
certified power factor must file a declaration with the Match Director stating the official ammo product will be in use for
the entire match. This declaration must be filed before starting the match.
Withdrawal of Declaration - A competitor who has declared he is using only official match ammo may withdraw the declaration by informing the
Range Master prior to use of any non-official ammo.
Ammo Samples - At any match where competitor ammunition will be chronographed, a competitor using official match ammo will be
required to provide eight rounds of this ammo at the time they pick up the ammo (delivery sample) and will also be
subject to the provisions of Appendix C2, “Competition Ammunition Collection”, Item 28.
Ammo Verification - At any match where competitor ammunition will be chronographed, a competitor using official match
ammo will have ammo samples collected during the match and chronographed according to the provisions of Appendix C2
#28. Should the ammo so tested fail to meet the declared power factor, it shall be compared against the average of
three rounds collected from the official delivery sample. If the samples collected during the match measure more than
10 power factor points below the delivery samples, the measured power factor of the ammo collected during the match
shall be used for score and the provisions of Appendix C2, Item 38 or Item 39 shall apply.
Unsportsmanlike Conduct - The use of ammo other than official match ammunition,
while declaring use of official ammunition, shall be considered unsportsmanlike conduct.
