Ladedaten-Spezifikationen
Ladedaten für Kaliber .257 Weath. Mag. mit Geschoss .257 | 80gr | Peregrine Plainsmaster (VLR-4) und 85 Pulvers. Die wichtigsten zugrunde liegenden Parameter sind in der obigen Tabelle dargestellt. Die empfohlenen Pulver für diese Patronen-Geschoss-Kombination sind Norma MRP, Alliant Reloder-26 und ReloadSwiss RS 70.
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 85 Pulver für das Kaliber .257 Weath. Mag. mit dem Geschoss .257 | 80gr | Peregrine Plainsmaster (VLR-4). Die höchste Mündungsgeschwindigkeit erreicht Alliant Power Pro 2000-MR mit 1.153 m/s; über alle Pulver hinweg liegt das Fenster zwischen 730 m/s und 1.153 m/s bei Maximallast. Den besten Hülsenfüllgrad liefert Accurate 3100 mit 100 %, und 85 der 85 Pulver liegen im gut nutzbaren Bereich von 80 bis 100 %.
Bezogen auf den zulässigen Höchstdruck des Kalibers (440 MPa) nutzen die Maximallasten 57 bis 90 % aus — es bleiben also mindestens 10 % Reserve. Für das 80,0 gr schwere Geschoss im Kaliber 0.257" wird ein Drall von 1:9.5 empfohlen — langsamere Dralle stabilisieren dieses Gewicht in der Regel nicht. Accurate 3100, Alliant Reloder-22, Alliant Reloder-23 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.
