The CCI capsules, being a soft, brittle plastic, could be hanging on a small burr or edge. I have not shot the rose crimp shells in many years, but, as you noted, they actually become longer after firing, and I suspect that they are at the outer limits of the capability of that action to eject shells. Since there will be a small variation in length, the longer ones then will hang up. Another factor may be the contour of the extractor hook. It may be too rounded to pull out the shell or it may be too shallow and riding up over the rim. Have a gunsmith check it unless you don't mind having to order another extractor if you file the old one too much. I once had the same sort of problem with a Mossberg 500 and reworking the extractor helped, but putting in a new one and a new spring finally cured the problem.
