Ladedaten-Spezifikationen
Ladedaten für Kaliber 8 x 57 IS mit Geschoss .323 | 200gr | Sako Hammerhead und 86 Pulvers. Die wichtigsten zugrunde liegenden Parameter sind in der obigen Tabelle dargestellt. Die empfohlenen Pulver für diese Patronen-Geschoss-Kombination sind ReloadSwiss RS 60, Alliant Reloder-17 und Alliant Power Pro 2000-MR.
Wichtiger Hinweis: Gehen Sie NICHT unter die Mindestladung oder über die Maximalladung. Da wir keine Kontrolle über die verwendete Ausrüstung und Komponenten haben, wird jegliche Verantwortung und Haftung für die erzielten Ergebnisse abgelehnt.
Es werden nur Pulver/Ladungen angezeigt, die den aktuellen Filterkriterien entsprechen: Maximaldruck einer Ladung ≤ 90% des standardisierten Maximaldrucks, Ladedichte ≥ 80% und Pulverabbrand ≥ 95%. Verwenden Sie die Schieberegler oberhalb der Tabellen, um diese Schwellenwerte anzupassen.
Ladung: Pulvergewicht in Grain. Beginnen Sie mit der Mindestladung und steigern Sie diese vorsichtig.
FR (Ladedichte): Hülsenfüllung in Prozent. Werte über 100% bedeuten komprimierte Ladungen.
MaxP / %: Maximaler Kammerdruck in bar sowie als Prozentsatz des standardisierten Maximums für dieses Kaliber.
V(0): Mündungsgeschwindigkeit in Fuß pro Sekunde (fps) bei standardisierter Lauflänge.
z (Pulverabbrand): Geschätzter Pulverabbrand in Prozent beim Austritt des Geschosses.
Für die Verwendung des personalisierten Ladungsrechners ist eine gültige Zugriffslizenz erforderlich.

Diese Übersicht vergleicht 86 Pulver für das Kaliber 8 x 57 IS mit dem Geschoss .323 | 200gr | Sako Hammerhead. Die höchste Mündungsgeschwindigkeit erreicht Alliant Power Pro 2000-MR mit 802 m/s; über alle Pulver hinweg liegt das Fenster zwischen 464 m/s und 802 m/s bei Maximallast. Den besten Hülsenfüllgrad liefert Accurate 4350 mit 100 %, und 86 der 86 Pulver liegen im gut nutzbaren Bereich von 80 bis 100 %.
Bezogen auf den zulässigen Höchstdruck des Kalibers (390 MPa) nutzen die Maximallasten 61 bis 90 % aus — es bleiben also mindestens 10 % Reserve. Für das 200,0 gr schwere Geschoss im Kaliber 0.323" wird ein Drall von 1:6.0 empfohlen — langsamere Dralle stabilisieren dieses Gewicht in der Regel nicht. Accurate 4350, Alliant Reloder-16, Hodgdon Hybrid 100V erreichen bei Maximallast 100 % Füllgrad oder mehr — diese Ladungen sind komprimiert, lassen sich nur mit langem Trichter oder Schüttfülltrichter sauber einfüllen und reagieren empfindlich auf die Hülsenkapazität deiner Charge. Ganz oben stehen ReloadSwiss RS 60, Alliant Reloder-17, Alliant Power Pro 2000-MR: Diese Pulver verbinden für 8 x 57 IS mit .323 | 200gr | Sako Hammerhead einen hohen Füllgrad mit vollständigem Abbrand und liegen bei der Mündungsgeschwindigkeit im oberen Feld. Beginne immer bei der Startlast und arbeite dich in kleinen Schritten nach oben, während du Hülse und Zünder auf Druckzeichen prüfst.
