I’ve been loading for about 3 years now. Started with 9mm and Lee dies. Learned a lot from this sight. I’ve been casting and loading for 30-06 for about a year and have been using Lee dies. The full length die seems to be extremely hard to use. I have stuck the some cases on the decapper/expander rod. These are RP cases, tumble cleaned. I brush clean the mouth and lube every case, mouth and body. I have to exert considerable force to get the cases off the expander. I recently started resizing some 303 British brass using RCBS dies. Wow. Total night and day difference. Hardly no effort to full length resize the case. This made me wonder if the lee decapper die is defective. I have it set to just kiss the shell holder on the up-stroke and the rod set to just push the primer out. I thought that was just the way it was with the lee die, till I used the RCBS. Iv started looking into replacing the lee dies with RCBS but wonder if it’s my setup/use of or the lee dies that’s creating the problem?
