USPSA Scoring

Documentation

• An excellent document covering scoring, database runs, etc is located here (PDF). It also contains the layouts of all the various classifier stages.
• USPSA Rule Books

Range Commands

From section 8.3 in the USPSA rule book

• "Make Ready"
• "Are You Ready?"
• "Standby"
• (start signal)
• "Reload If Required And Holster" (for strings)
• "If You Are Finished, Unload And Show Clear"
• "If Clear, Hammer Down, Holster"
• "Range Is Clear"
• "STOP!" (if necessary, at any point)

Points of interest:

• There is NO "Range Is Safe" command -- The range is never safe while there are people with firearms on the range.
• There is no "If Clear, Striker, Holster" command -- All firearms are considered to have hammers, regardless.
• There is no "Reload If Necessary And Reholster A Hot, Safe Weapon (or Firearm)" command -- Under USPSA terminology, there is no such thing as a loaded firearm that is safe.
• Competitors are expected to know that if a firearm has a manual safety (1911-style), it must be engaged before holstering, whether start of COF, or within a string.
• No range commands use the term 'firearm', 'weapon' or 'gun'. The USPSA also discourages the use of the word 'weapon', and prefers 'firearm', 'pistol', or 'gun'.

Target Scoring

Zone	Major	Minor
A	5	5
B	4	3
C	4	3
D	2	1
M	-10	-10
NS	-10	-10

Hit Factor

Hit Factor = Points / Time
Points = Time * Hit Factor
Time = Points / Hit Factor

Power Factor

Class	Power Factor
Major	165
Minor	125

bw = Bullet weight (in grains)
pf = Power factor
mv = Muzzle velocity (in feet per second)

pf = (bw * mv) / 1000
mv = (pf / bw) * 1000
bw = (pf / mv) * 1000

Examples:

• To make a power factor of 170 with a 230gr bullet, we need 730 fps muzzle velocity
• To make a power factor of 170 with a 124gr bullet, we need 1371 fps muzzle velocity
• To make a power factor of 130 with a 124gr bullet, we need 1049 fps muzzle velocity

Divisions

• Carry Optics (minor only)
• Limited (major, minor)
• Limited 10 (major, minor)
• Open (major, minor)
• Pistol Caliber Carbine (minor only)
• Production (minor only)
• Revolver (major, minor)
• Single Stack (major, minor)
