Yes, there are two different lengths of 38-55 brass, the long 'original length' intended for original rifles of yore (which is too long for mine) and the shorter, which most currently available is.
There are also variations in the neck thickness, which the thicker WW in a tight chamber, will do exactly what you are experiencing. I have to neck turn just the area of the neck to bullet base depth a few thou' to get good ejection. You can experiment on a problem case by hand filing around the neck of a 'sticky' fired case and retrying it until it chambers loaded and ejects and ejects when fired. That identifies the culprit. If that is what is happening, you need the thinner necked Starline, or rework yours.
So, 1st make sure the length of brass is right
2nd, make sure the case neck has a couple of thou' clearance
