About 20 Bore Shotguns

The 20 bore is the second most widely used shotgun gauge in the United Kingdom after the 12 bore, offering lighter weight and reduced recoil while retaining practical performance for game shooting and clay sports. It is a popular choice for women, younger shooters and experienced guns who prefer a lighter carry on walked-up or rough shooting days.

 

The gauge fires a 65 or 70mm shell with a payload typically between 24g and 28g, effective on pheasant, partridge and pigeon at standard driven distances. All 20 bore shotguns require a Shotgun Certificate (SGC).

 

Major manufacturers producing 20 bore guns include Browning, Beretta, Miroku, Caesar Guerini, Krieghoff and Perazzi, with the used market spanning from entry-level Spanish and Turkish guns under £500 to high-grade Italian or English over-and-unders above £5,000. Setting up a Gunstar alert for your preferred spec is a practical way to track availability.
