Frequently asked questions

Can a 12/89 cartridge be fired from a 12/76 shotgun?

No. This cartridge may only be used in a firearm clearly marked for a 12/89 chamber. Firing an 89 mm cartridge from a 70 or 76 mm chamber is dangerous because the case cannot open correctly.

Is it suitable for every 12/89 shotgun?

In addition to an 89 mm chamber, the firearm must be proofed for high-performance steel-shot ammunition. The barrel and choke must also be approved for steel shot. Always follow the firearm and choke manufacturers’ instructions.

Is the Mirage T3 Supermagnum lead-free?

Yes. It uses soft-steel pellets and is intended for hunting in areas where the use of lead shot is prohibited.

Which shot sizes are available?

Clever lists shot sizes No. 1, 2, 3 and 4. The shot size of the specific cartridge must always be checked on the packaging. Selection depends on the quarry, shooting distance, firearm pattern and applicable regulations.

Why does it use a 39 g payload?

Steel is less dense than lead. A heavy 39 g payload allows the cartridge to carry more pellets and helps produce a denser pattern. It will generally generate more recoil than a 28 or 36 g load.

Is it suitable for very long shots?

Clever describes the cartridge as suitable for longer-distance shooting, but no fixed range can be determined from the cartridge alone. Performance depends on shot size, barrel, choke and weather conditions. Practical range must be established through pattern testing and kept within reliable, ethical limits.

When is Mirage T3 Supermagnum the right choice?

This cartridge is intended for hunters who own a steel-shot-approved shotgun with an 89 mm chamber and require a heavy lead-free load for duck or goose hunting. Its 39 g payload is designed to produce a dense pattern where a lighter 28 or 32 g steel load may be insufficient.

Choose a 12/76 or 12/70 cartridge if the shotgun has a shorter chamber or lower recoil is a priority. T3 Supermagnum is a specialised hunting load rather than a general-purpose training cartridge.

Expert recommendation

Before use, check the chamber-length and steel-shot proof markings on the shotgun. Do not assume that every 12-gauge firearm—or even every 12/89 shotgun—is automatically suitable for all steel loads. The choke must also be approved by its manufacturer for steel shot.

Pattern the selected shot size with the same shotgun and choke that will be used in the field. A heavy 39 g payload does not automatically guarantee a suitable pattern, and different pellet sizes can produce noticeably different results from the same firearm.

A heavy lead-free load for waterfowl hunting

The Mirage Soft Steel T3 Supermagnum combines a 39 g soft-steel payload, an 89 mm case and a dense pattern intended for longer-distance shooting. It is a specialised hunting cartridge for compatible 12/89 steel-shot-approved shotguns.
