- USPSA Rule Books
From section 8.3 in the USPSA rule book
- "Make Ready"
- "Are You Ready?"
- (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'.
Hit Factor = Points / Time
Points = Time * Hit Factor
Time = Points / Hit Factor
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
- 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
