Hello, I'am new to reloading, but i already strugle with the case rezising. I use the full resizing tool from Lee, i use Lee Lub and my case are crystal clean. But each time i got some bump on the case, could it be my fault, or might it be a faulty tool ? I tried 4 times, 4 times the same happend, if i put again and again the same case, there is more and more "bump" I tried to put different amount of lub, still happening. Btw with those bumps, is it safe to still fire them ?
