Was founded in 1991 by Mike and Sharon Higashi, long time active shooters in all the handgun sports. Envisioned as an alternative to the "arms race" that was occurring in the other action shooting sports at that time, a revolver-only competition would allow even the most basic equipment to be used and still provide enjoyment and satisfaction. ICORE combines elements of the Bianchi Cup, IPSC, and the Steel Challenge into demanding competition exclusively for revolvers.

The targets and scoring are different as well with scores outside the A Zone incurring a time penalty. Limited Division competitors use essentially stock pistols, whereas in Open Division, various modifications are allowed. A new division called Classic has been created to cater for 6-Shot revolvers using speed loaders.


Along with your revolver you must also have a holster, loaders and loader holders. You can use either speed loaders, or moon-clips to load the revolver.

All revolvers used in ICORE must be .32 magnum calibre or greater. Ammunition must meet a power factor of 120000.

ICORE has three divisions in which govern what revolver modifications you can have.

You must compete in “OPEN” if the revolver has one or more of the following modifications.

A. Compensating, venting, or metering ports of any kind.

B. An optical sight including telescopic and red dot sights.

C. A rib sight, a front sight that extends beyond the muzzle, or a rear sight that extends beyond or behind a factory
manufactured sight's location.

D. Any barrel other than an unaltered factory barrel or an unaltered factory replacement barrel made by the revolver’s manufacturer. Alterations to the barrel other than what is required to safely install the barrel are not permitted in Limited Division.

E. An underlug, barrel weight, grip weight, or any other modification designed to increase the weight of the revolver.

If your revolver does not have any of the modifications just mentioned then you will compete in “Limited”

A Classic Division revolver is a Limited Division revolver that has the following additional requirements:

A. Cylinder with only 6 chambers.
B. Must only use speed loaders to reload. Moon-clips are prohibited.

The standard paper target is the NRA D-1 target with 4 scoring areas. Scoring is based on time, including time added or subtracted per shot depending on which scoring zone it hits.

X-Zone – Bonus Score, Subtract 1 (one) Second if designated in stage description, if not counts as an A-Zone.

A-Zone - Adds no extra time.

B-Zone - Adds 1 (one) Second.

C-Zone - Adds 2 (two) Seconds.

Miss - Add 5 (five) Seconds.

Falling and stationary steel plates are also used in ICORE events.

Course Of Fire

In ICORE the match is consisted of multiple stages. Each stage is designed and set-up prior to the commencement of the match. The course of fire is individual to each stage. Stages may consist of paper and/or steel targets arranged in any manner, as long as range safety is not compromised.

Stages can involve movement and/or static shooting from boxes.
