Je veux faire des essais avec ma 300 SAUM.
J'ai des boulets 165 grains Hornady.
Quelle serait la recette de départ avec de la poudre Hodgdon 4350 ou de H-414, ou 44831?
C'est juste pour essayer car j'ai une bonne recette pour le 180 grains.
Question de faire des essais?
merci

Aie, merci MooseTracker,
