Bezołowiowe Pociski Hasler Hunting 7,62 mm (.308), 154grs

Hasler Hunting line feature frangible hunting-oriented bullets. These are ogives made in the HPBT design, whose outer structure is the same as the structure of the ones designed for precision shooting. The only difference is the dimension of the apical hole and the presence of three or four broached grooves in the pit itself which weaken the structure making the opening more consistent. This, combined with the excellent quality of the copper we use, offers significant advantages even in hunting, as you’ll reach a perfect balance between precision, terminal effect and defense of the flesh of the animal. The consistent expansion of the bullet guarantees the killing of the animal without spoiling it.

Hasler Monolithic bullets, with their characteristic o-ring structure, offer an excellent ballistic coefficient.

Tips for reloading with Hasler bullets

Hasler bullets may have two O-rings and one Pilot O-ring, or three O-rings and one Pilot O-ring.

The Pilot O-ring has a different form and it is at the edge of the bullet, its function is to make the insertion of the ball into the barrel the more coaxial as possible, in order to gain the highest precision.

During the assembling process, it is crucial that at least two o-rings are kept inside the neck (see explanatory image).

The neck must be re-calibrated for at least 2/3 of its length; if you re-calibrate it through its whole length, it is even better.

The neck must offer sufficient strength to firmly retain the ogive. For ogives long as the 30/168/Ariete and 7/152 Ariete, a slight crimping with ”LEE Factory Crimp Die” is a good idea to improve the combustion of gunpowder. With semi-automatic weapons, it is desirable to do a light crimping or a narrower calibration of the neck.

If you are using dies with the bushing, you have to position them so that there is still enough room for the o-rings inside the neck.

Freeboring: this parameter is crucial for shooting precision, usually in almost every caliber you reach a freeboring between 1 and 2mm. You’ll obtain maximum precision inside this range. It is possible to modify the distance between the two O-rings, as long as they stay inside the collet.

Hasler ogives offer low bore fiction and, as a consequence, lower counter-pressure. That’s why they’ll require a little more lively powders to reach the right pressure needed for the perfect combustion of the powder itself.
