As the titles says im trying to find .510cal projectiles for my 50bmg from sellers in Australia. Can anyone help me out? Specifically after Hornady A-max's if possible, but will appreciate info on where to get any brands. Preferably somewhere that sells boxes( so i can get them at a decent price). Also does anyone know what the procedure is to be able to import some from America? Thank you, Aus50bmg.gun)
