223 bullet drop die

works great

need a 4mm steel bb 2 springs approx 16mm long with 4mm loops or hooks and some tube with 10mm od can modify model to take what ever tube you want pretty easily

to set just put case in press at max height and screw down till bullet drops doesn't take much, have been using with 55gn v-max projectiles may need tweaking for bigger rounds give me feed back if so
