I'm going to start reloading for my .40S&W (Springfiled XDm). The 40 and 10mm are the same diameter bullet .400. I've checked the local stores here in valley/Anchorage area and have found some lead for the 10mm but little for my .40.
My question is with the diameter being the same, can you buy "10mm" lead and push it through my .40???
