- Pour MooseTracker; Le canon a 24 . Pour le choix des boulets, Nosler sera toujours mon fournisseur pour mes boulets réservé pour la chasse. J'ai des Accubond, Partition en masse et une boite de E-Tip tous en 180grs.
Cette carabine servira uniquement pour la chasse à l'orignal et le caribou. Des bûchers c'est grand et les distances sont longues. L'accubond a un meilleur Cb que le Partition et j'envisage des possibilités de tirs dépassant 500v avec cette arme!
En théorie, pour un canon de 24" les sweet spots devraient etre a 1.102 milliseconde et 1.228 ms.
J'ai fait une simulation Quickload pour une canon de 24" a une température de 70*F au maximum de pression de 63,817 psi. Voiçi ce que ça donne:
Cartridge : .300 Weath. Mag.
Bullet : .308, 180, Nosler AccuBond 54825
Useable Case Capaci: 87.045 grain H2O = 5.652 cm³
Cartridge O.A.L. L6: 3.560 inch = 90.42 mm
Barrel Length : 24.0 inch = 609.6 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63817 psi, or 440 MPa
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !
104 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.
