Bonjours à tous,

Est-ce que quelqu'un à des recettes à me donnée pour un calibre 6mm BR pour un boulet de 90 grains. J'en ai quelques'une mais je voudrais en essayer d'autre, cependant nous avons peu d'information dans les livres de recette sur ce calibre.

Merci

Richard

Quel boulet de 90grs utilises-tu?

salut les gars,

j'utilise des boullet Lapua scenar 90g , 0.243

salut

Tu pourrais commencer par consulter l'article et les recettes fournies sur le lsite suivant;
http://www.6mmbr.com/6mmbr.html

Ensuite, une simulation Quickload avec un boulet Scenar de 90grs a une température de 70*F dans un canon de 26" donne les résulatats suivants pour différentes poudre au maximum de pression pour ce calibre:

Barrel Length : 26.0 inch = 660.4 mm

Predicted Data for Indicated Charges of the Following Powders.

Matching Maximum Pressure: 58740 psi, or 404 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.
