Ladedaten-Spezifikationen
Ladedaten für Kaliber 6.5 x 64 Brenneke mit Geschoss .264 | 123gr | Sierra MatchKing und 87 Pulvers. Die wichtigsten zugrunde liegenden Parameter sind in der obigen Tabelle dargestellt. Die empfohlenen Pulver für diese Patronen-Geschoss-Kombination sind Alliant Reloder-26, Accurate High Country und Norma MRP.
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.

Den besten Hülsenfüllgrad liefert Accurate 3100 mit 100 %, und 87 der 87 Pulver liegen im gut nutzbaren Bereich von 80 bis 100 %.
Bezogen auf den zulässigen Höchstdruck des Kalibers (430 MPa) nutzen die Maximallasten 58 bis 90 % aus — es bleiben also mindestens 10 % Reserve. Für das 123,0 gr schwere Geschoss im Kaliber 0.264" wird ein Drall von 1:9.0 empfohlen — langsamere Dralle stabilisieren dieses Gewicht in der Regel nicht.
