STS empty's are made in one piece never see this line. Is the line a reason to reject that shell ? Cut a few open they seem sound with the line

Bill many times when you see auctions for empty AA hulls some sellers will state "old style", which in my opinion are better than the "new" style AA which have a tendency to produce this line around the hull. It's because they are a two piece hull and the old style was one piece of plastic. The newer hulls came out quite a while ago, early 2000's maybe, I forget. Anyway when they came out many people including myself suddenly started seeing this in their reloads. The problem was so prevalent Winchester has the following information on the reloading portion of their website.
How can I get a good crimp with the new 12-gauge AA high strength hull?
Winchester has designed the new 12-gauge AA high strength hull to reload with the same reloading data as the old AA hull. However, on some reloading machines, even though the components and reloading data are the same, there may need to be a minor crimp station adjustment made. Please contact your reloading machine manufacturer if you need assistance adjusting your crimp station. Shooters have found that after making a slight adjustment to the reloading machines good quality crimps and long reloading life are consistently obtained with the new AA high strength hull.
If I remember correctly the adjustment to eliminate this line is moving the pre-crimp station down so it nearly closes the hull and moving the final crimping station up until it's just enough to close the mouth of the hull.
The STS hulls load like the "old" AA's and IMO are a superior hull. As far as shooting the hulls with the lines I have shot lots of them over and over without issue. I hope this helps.
