Hirtenberger 7x65R - A little history.
La Austrian house Hirtenberger was born in 1860 when the percussion muzzle loader was flanked by the first breech-loading ammunition for the needle system, made famous by the Dreyse rifle, and shortly after the metal case cartridge as we know it today dominated the scene. Business development is favored by residing in the Austro-Hungarian Empire, the largest territorial expression of old Europe, with an army of enormous proportions. The events of the twentieth century dismember this political ensemble, but they do not stop the business development that carefully follows the civil sector as well as the military one with the superb period of high hunting inserted between the two wars. It is the time of the deer with phenomenal trophies and tonnage: they are often hunted with this caliber which is recognized as having an authoritative stopping power even at considerable distances. The 7 mm is considered the golden measure of the bullets and the technical setting given by Wilhelm Brenneke to this cartridge, born among other things 101 years ago, provides a very short rifling pitch of 1: 8,6 (220 mm), suitable for correctly stabilizing bullets weighing 11,5 g, therefore equipped with a high sectional density to which is added an above average speed, slightly lower than subsequent magnums of the same caliber; the differentiation made by the German designers between the rifle cartridge and the homologous swing-action cartridge appropriately sees a little less for the latter, but there is little difference. Penetration into large-scale game is ensured and the transfer of energy, at this point, is entrusted to the structure of the projectile: already at the time the designer proposed a series with a different structure for the different game heads and are still today at the top of the sector.
Hirtenberger 7x65R - The company today.
In recent times, the corporate brand is incorporated into the Ruag Ammotec GmbH and in Fürth, near Nuremberg, the company has a production plant for the highest quality cartridges: by visiting it you are aware of the meticulousness applied in the processing and in the control by a highly qualified workforce. Meanwhile, even in the United States of America, the study of hunting and shooting bullets has made great strides with excellent results in external and terminal ballistics which is joined by the appreciable implication of affordable prices (at least until some time ago). Hirtenberger's choice of adopting a bullet inserted for many years in the preferences of hunters is therefore appropriate: the Nosler Partition certainly needs no introduction, but it is worth remembering its external shape with cylindrical body, open base, tapered ogive with pointed apex. in bare lead, factors that favor its stabilization by passing through the rifling, creating the conditions for a constant and appreciable intrinsic precision. To this is added the well-known internal structure thanks to the casing that closes about halfway through the bullet, separating the internal lead mass into two distinct entities: the straight section shows an H with the central dividing septum. Upon impact with the wild, there will be a mushroom-like expansion of the front part, where the original diameter is doubled, creating the petals turned up on themselves by the jacket; at the same time the rear part remains intact acting as a push element for the crossing of the wild.
Hirtenberger 7x65R - The cartridge
It should be noted that the company ensures these effects even at residual speeds of around 570 m / sec, therefore at considerable distances. The ball mounted on this cartridge it has a weight of 9,1 g (140 grs), an intermediate value for the 7x65R with which a good trajectory voltage is obtained: the rangefinders and some current optics allow the rapid correction of the aiming according to the distance and therefore the fall of the ball , nevertheless it is always favorable to be able to take advantage of a quick aiming knowing how, within certain limits, it is sufficient to position the cross more or less high, but always within the target, with the certainty that the shot will end where it should.
Hirtenberger 7x65R - Ammunition on the hunt
The practical table printed on the package indicates 180 m as GEE, the most favorable zeroing distance for not having a hit point greater than 4 cm, and here it occurs right at 100 m: with this calibration they correspond to -2,5 cm at 200 m, -12,5 cm at 250 m –28 cm at 300 m therefore a sensible range of use to undermine from chamois to red deer with the interlude of roe deer, whose shell is not ruined, to mouflon, fallow deer and wild boar.
