This is the what the instructions in my 550 said to do. You paid big bucks for a Dillon so you might as well do what they say and let them send a new one.
That tube is really soft aluminum. If you had to poke very hard at all, you may have a burr or a depression inside the tube. That will probably cause more problems later. Even though Dillon will send a replacement out for free, I bought extras just to avoid down time. Glad it worked out for you this time.
thank you for this. had one jam with wlp and have taken long steel punch and hammer to TRY to get it out...no luck. didnt think to call them, but they have been great on everything i have contacted them about.
