The Shotgun Divisions List


Open Division

1 Minimum power factor 480
2 Minimum shot weight No
3 Minimum caliber 20 gauge / 20 bore
4 Maximum shotgun weight No
5 Minimum trigger pull No
6 Restriction on action types No
7 Magazine length restrictions Yes, see point 16. Also, detachable magazines of a length up to 12 total capacity
8 Detachable magazines Permitted
9 Magazine capacity restrictions Yes, see point 7
10 Speed loading devices Permitted
11 Modifications/attachments to loading port floor plate Permitted
12 Compensators, sound and/or flash suppressors Permitted
13 Ports Permitted
14 Optical or Electronic sights Permitted
15 Barrel heat shields Permitted
16 Maximum overall length for complete gun 1320mm
17 Modifications allowed Yes
18 Factory produced guns only (minimum 100 units) No

Special Conditions:

  1. Prototypes are allowed.

  2. Open Division is subject to an overall maximum length of the gun. The gun in its fully loaded ready condition and with any extended magazine tube fitted must fit into a rectangular shaped boxed which is open on one long side. The internal dimension of this box must be 1320mm long (with a tolerance of : +1mm, -0mm). The shotgun is to be placed in the box with the barrel parallel to the one long edge. However, for reasons of safety and expediency the test will usually be carried out with the gun unloaded providing the overall gun size remains the same whether loaded or unloaded. The Range Master’s decision on this matter is final. The gun must not be artificially compressed in any way during the test solely for the purpose to fit in the box.

2 Minimum shot weight No
3 Minimum caliber 20 gauge / 20 bore

18 Modifications allowed. Restricted, see below. Permitted

Special Conditions:

  1. Modified Division is subject to an overall maximum length of the gun.

    • Checkering of frames, stocks and fore-ends.
    • Cosmetic enhancements that do not give a competitive advantage such as custom grips, plating, etc.

  6. Internal modifications to improve accuracy, reliability and function are allowed.

  7. Additional cartridge loops or clips, specifically including side saddles, may be fitted to the stock, fore-end, receiver or sling (providing they do not compromise any safety issues).
