Not sure where to post this…. Is it possible to vary the case volume of a group of rifle cartridges by placing a molten alloy of lead/ tin/ antimony in the cases and then drilling thru the alloy with different diameter drills to leave a series of cylindrical voids within the cases to allow various volumes of powder to be placed and allow the projectile to be seated on the powder column? I’m currently using the .30-06 with several different brands of brass.The cases weighing from roughly 180 grains to 200 grains for loading duplex charges (4227/WC 860) and the resulting velocity is around 2500 F/S which is too fast for the boolit alloy and barrel twist rate (1/10”). I intend to reduce the powder / case volume in increments until I reach a reduction in velocity where accuracy is obtained. By stopping the height of the alloy at the bottom of the shoulder I will try to prevent the alloy from moving within the case. I intend to place the case in water to prevent the softening of the case head from the heat of the molten alloy. I will place a straight finishing nail thru the primer flash hole to create a guide hole for the drill bits to allow alignment with the primer flash hole. It is necessary to seat the boolit against the top of the powder column in order to prevent the “kicker” 4227 granules from being mixed into the 60 grain charge of WC 860…
