So as I was waiting to get my barreled action I went down the rabbit hole of data for the LBCR sabots and long 40 cal bullets. I kept reading about the need for a cooling rod to speed up barrel cool down. I was finally able to punch in the right word combo to find some ideas on dougs messageboard. So now I have a 7/16in cooling rod and stand put together. A buddy then asked me if you put a chilled rod down a hot barrel wouldn't that add extra stress to the barrel cooling it down so quickly? I told him I had no idea. So school me on how a cooling rod should be used, and/or could it be harmful to the barrel? TIA
