The targets should remain edged between all strings and until all issues are addressed, if possible (more on this below). Inadvertent facing of the targets before the range is cleared for normal scoring can create problems and actually create conditions wherein options are removed from the shooter. (see below)
Perry and all major matches I've ever been to DO NOT face after the first 5 shot string unless there is a range problem or inadvertent operation.
If the targets face after the first 5 shot string, there will be a problem when a less than required time "range alibi" occurs.
In this type of "range alibi" situation the shooter supposed to be provided with the opportunity to make a decision on taking a refire string or not to take a refire when less than the required time is presented. For example, in time fire (20 seconds) the range control malfunctions and turns in 10 or 15 or even 19 seconds. This is a "range alibi" just like allowing too much time (which has different option, see below).
When too little time is allowed, the shooters have the option, without viewing the targets, to accept the rounds as fired or take the range alibi refire string. If the targets are faced during corrections or after the malfunction (allowing some shooters to see their targets), generally a complete refire is called and shooters do not get a choice. (Therefore the facing of the targets so the shooters can see them actually removes an option from the shooter that would be interpreted from the rules. Please read the rules and description of range alibis and operations.)
9.12 Interruption of Fire -
(a) In timed or rapid fire when the firing of a string is interrupted
by some occurrence which renders it impossible
for one or more competitors to complete the string under
the conditions of the match, the Chief Range Officer will
proceed as follows. Without being permitted to examine
their targets, competitors in the relay who have been so
prevented from completing their strings will be asked if
they wish to refire or to accept their score as fired. Targets
will then be scored in the usual manner for all competitors
except those who have elected to refire. Without being
scored, the targets of such competitors who have elected
to refire will be pasted or new targets substituted and a
complete string will be fi red and scored.
Situations where longer than the required time is provided is also a range alibi, but the shooters do not get a choice. Everyone is supposed to refire.
9.12 (b) In timed or rapid fire when, due to faulty target operation
or error in timing, one or more competitors are
allowed more time to complete the string than provided
by conditions of the match, the Chief Range
Officer will immediately order all such targets pasted
or new targets installed. The fired target will not
be scored. A complete new string will then be fired
by the competitors who are allowed extra time. If in
the same relay some targets operate properly in accordance
with the legal time limit, such targets will
be scored in the usual manner and competitors firing
on those targets will not be required or permitted to
There are some other situations, especially on split ranges (like Perry) when there may be two different types of range alibis on either side of the range. That really gets interesting.
