I need help from those who own or have access to draw sets from “larger diameter” (i.e. ammo bigger than .25 cal) rimfire or pinfire ammo for a research project I’m working on. I already have good measurements from a 56-56 Spence set. I can provide the equipment for you to collect the measurements (i.e. digital scales for weight and calipers for size measurements). Let me know if you are interested in this effort.
