I have two Lee #11 shell holders. One came with a 44mag/44spl three set. The other with a 45 Colt three die set. One is just plain out of spec. I've never replaced it and I just use the other one for both cartridges.
I have broken a Lee "unbreakable" decapping die. I found out Lee has excellent customer service. Im sure they'll send you a new shell holder without question or delay.
