Ladedaten-Spezifikationen
Ladedaten für Kaliber .25 GT mit Geschoss .257 | 90gr | CutEdge ER Raptor und 86 Pulvers. Die wichtigsten zugrunde liegenden Parameter sind in der obigen Tabelle dargestellt. Die empfohlenen Pulver für diese Patronen-Geschoss-Kombination sind Hodgdon CFE223, Alliant Power Pro 1200-R und Winchester 748.
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 .25 GT mit dem Geschoss .257 | 90gr | CutEdge ER Raptor. Die höchste Mündungsgeschwindigkeit erreicht ReloadSwiss RS 52 mit 960 m/s; über alle Pulver hinweg liegt das Fenster zwischen 561 m/s und 960 m/s bei Maximallast. Den besten Hülsenfüllgrad liefert Accurate 2495 mit 100 %, und 86 der 86 Pulver liegen im gut nutzbaren Bereich von 80 bis 100 %.
Bezogen auf den zulässigen Höchstdruck des Kalibers (427 MPa) nutzen die Maximallasten 54 bis 90 % aus — es bleiben also mindestens 10 % Reserve. Für das 90,0 gr schwere Geschoss im Kaliber 0.257" wird ein Drall von 1:8.0 empfohlen — langsamere Dralle stabilisieren dieses Gewicht in der Regel nicht. Accurate 2495, Accurate 4064, ADI AR 2208 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 Hodgdon CFE223, Alliant Power Pro 1200-R, Winchester 748: Diese Pulver verbinden für .25 GT mit .257 | 90gr | CutEdge ER Raptor 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.
