My fire arm is a rare LWR ar-15 based .499 caliber rifle
I have one Cartridge from a collector web site... I have 100rounds of brass.... dies from RCBS and a press ..... and I would like to get projectiles to make more rounds from my brass. The diameter of the projectile is .499 ... would a 0.500 round work for reloading at .001 difference ? Or does anyone know who might have molds to make anything ?
