Cartridge portrait: GECO HEXAGON, the ideal match cartridges for pistols and revolvers in four calibers

As far as equipment is concerned, sport shooting not only depends on excellent and smoothly functioning firearms, but also on the ammunition that shoots accurately. Although the 9mm Luger and .45 ACP pistol cartridges may have military origins (and are still used by the military and in law enforcement), both calibers have also been at the forefront of large-caliber competition shooting for decades. Likewise, the two most popular revolver cartridges in .357 Magnum and .44 Magnum have a firm fan base. And all four are also capable of producing tight groupings and performing reliably and evenly even in fast shot strings in action shooting.

Ambitious shooters also consult the "groups" that can be achieved from clamping the gun in a rest to assess shooting performance. Equally important, however, is the feel when shooting from freehand (usually two-handed in IPSC): recoil should be even and not too rough so that the shooter can still judge the sight adjustment "through the fire" and correct it if necessary.

For years, GECO's HEXAGON handgun ammo line has been a classic in terms of popularity and reliability (although the two are closely linked). The name Hexagon (Greek for hexagon) comes from the characteristic six stabilization grooves that characterise each bullet. In this cartridge portrait, we want to list the key specs of the four currently available loads and name the factors why it is worth using high-quality ammunition in the large-caliber sports sector and using the notorious and at best somewhat cheaper "bulk packs" for training at best. Let's be honest: who wants to save money at the wrong end and lose a competition because of an ammunition mishap?

The components of the GECO HEXAGON cartridge (here in sectional view)

1. Advantageous aerodynamic shape
The almost closed tip is aerodynamically advantageous as it ensures a longer trajectory with less reduction in velocity.
2. Six stabilisation grooves
The six long grooves create what is referred to as the golf ball effect. This means that the air vortex created by the rotation around the longitudinal axis provides additional stablisation of the projectile in flight.
3. Optimised centee of gravity
The center of gravity is shifted to the rear, contributing to the improvement of accuracy.
4. Improved barrel guidance
The long cylindrical projectile section achieves better barrel guidance.
5. High accuracy casing
With even wall thickness and optimised concentricity.
6. High-performance powder
For consistent velocity development and reduced burn-off temperature.
7. Closed bullet base
For shooting without lead emissions.
8. NATO-approved SINTOX primers
For ignition free of heavy metals.
