GECO offers five different bullet lines in a wide range of calibers
All GECO rifle cartridges for hunting are available in a wide range of calibers:
.222 REM. / .223 REM. / .243 WIN. / 6,5 CREEDMOOR / 6,5x55 SE / .270 WIN. / 7x57 / 7x57 R / 7MM REM. MAG. / .280 REM. / 7x64 / 7x65 R / .308 WIN. / .30-06 / .300 WIN. MAG. / 8x57 JS / 8x57 JRS / 9,3x62 / 9,3x74 R
What does the calibre mean in hunting ammunition?
Metric calibre designations: the example of 7 x 64
For rifle cartridges with metric calibre designations, the designation usually consists of two numbers. How these figures are to be understood can be clearly explained using the example of the 7 x 64 calibre.
The first number – in this case 7 – refers to the nominal calibre of the bullet or the barrel. The second number – 64 – indicates the case length in millimetres. The designation ‘7 x 64’ therefore describes a nominal calibre of 7 mm and a case length of 64 mm.
The nominal calibre is a rounded value. It is based on two different measurements of the barrel: the face diameter and the rifling diameter. For the 7 x 64, for example, the face diameter is 6.98 mm, whilst the rifling diameter is 7.24 mm.
These different measurements result in the rounded and easily understandable nominal calibre of 7 mm, which forms part of the metric calibre designation ‘7 x 64’.
Unambiguous calibre designation for rifle cartridges
The unambiguous calibre designation of rifle cartridges is a key factor in the safe and unambiguous identification of ammunition. Among other things, it serves to prevent confusion between calibres and types of ammunition.
For each rifle barrel, only ammunition of the calibre for which the barrel is designed and accordingly marked is permitted. Therefore, the calibre designation of the rifle must be clearly identifiable. The exact calibre designation is permanently marked on the barrel and on other essential parts of the rifle.
The correct matching of calibre and ammunition is crucial: only cartridges whose calibre matches the rifle’s marking may be fired from the respective barrel. Clear marking thus helps to prevent mix-ups with rifle ammunition and ensure safe handling.
Choosing the right hunting ammunition
Choosing the right hunting ammunition is a key part of successful and responsible hunting. Which ammunition is suitable depends on various factors: the type of game, the shooting distance, the calibre and bullet type used, the applicable legal requirements, and the hunting rifle used.
But which hunting ammunition is suitable for which situation? And what should you look out for when making your choice? The following points provide an overview of the most important criteria.
Choosing hunting ammunition suitable for the type of game
The requirements for the ammunition used vary depending on the type of game. When selecting a hunting cartridge, you should therefore first consider which game you intend to hunt.
For roe deer, wild boar and red deer, different requirements regarding bullet performance and design may apply depending on the hunting situation. When hunting predatory game, too, calibre, bullet and the desired effect play an important role.
It is crucial to choose hunting ammunition that is suitable for the specific game species and the particular hunting situation. In doing so, in addition to the characteristics of the ammunition, the legal regulations and the requirements of the respective hunting area must also be observed.
Selecting hunting ammunition according to shooting distance
The shooting distance also influences the choice of suitable hunting ammunition. A cartridge that is suitable for classic stand hunting is not necessarily the best choice for a driven hunt or longer shooting distances.
In stand hunting, the focus is often on precise shooting and reliable bullet performance. In driven or moving hunts, however, different demands may be placed on the ammunition and the bullet.
For hunting at longer ranges or long-range applications, additional factors such as bullet shape, ballistics and wind sensitivity play an important role. The greater the distance, the greater the impact of bullet velocity and trajectory on the point of impact.
Take calibre and bullet type into account
Another important criterion when selecting hunting ammunition is the calibre. The ammunition used must, of course, match the calibre of the hunting rifle. The clear calibre marking on the rifle and the cartridge helps to prevent mix-ups.
In addition to calibre, the bullet type is also crucial. Different bullet designs can vary in terms of their properties and their effect on the game’s body. Therefore, the choice of bullet should always be suited to the specific game species, type of hunt and shooting distance.
Anyone wishing to choose their hunting ammunition should therefore not focus solely on the calibre, but consider the interplay between calibre, bullet design and hunting application.
Lead-free or lead-containing hunting ammunition?
When selecting the correct hunting cartridge, the applicable legal requirements must also be taken into account. In various regions and for different hunting situations, there may be regulations governing the use of lead-free hunting ammunition.
Anyone using lead-free ammunition should take particular care to ensure that it is suitable for their own firearm and reliably achieves the required accuracy. Before use, one should therefore check which legal provisions apply at the respective hunting location.
Consider the firearm and barrel length
Not all ammunition is equally suitable for every hunting firearm. When making a selection, therefore, the firearm and barrel length should be taken into account in addition to the calibre.
The barrel length can influence the ballistic properties of a cartridge. In particular, with different barrel lengths, factors such as bullet velocity and point of impact may vary. It is therefore advisable to test the hunting ammunition with your own firearm and to check the point of impact before using it for hunting.
The right hunting ammunition for every situation
Choosing the right hunting ammunition therefore depends on several factors. The type of game, the type of hunt, the shooting distance, the calibre, the bullet type, legal requirements and the firearm used should all be taken into account equally when making a decision.
By weighing up these criteria and carefully testing the ammunition with your own rifle, you lay an important foundation for precise and responsible hunting.
GECO offers a wide selection of hunting ammunition for various calibres and hunting requirements. This allows you to select the right cartridge specifically tailored to your own rifle and the intended purpose.
