Hey Brad, it's a Shimano internal cam skewer. I literally don't think I can tighten it down much harder.

So the skewer thread is fully engaged in the new Campagnolo road skewer that you found.
The lock nut on the end of the axle should have the gripping surface, so the cap does not need it, as well ..
those skewers with a much longer dropout worked well ,
doubt you put out the power of an Eddy Merckx in his prime, and that gear worked on his bikes.
I could crush Eddy in his prime! J/k
I think the skewer is seating just fine in the cap.

BTW. I had an '87 560 for many years and, using a shimano skewer, never, ever, had the rear wheel slip.
1) Already did that.
2) It's a nice Shimano QR but I do have a different cap that has a few serrations on it that I could try.

Now here's how to improve the bite. Get some medium/course sandpaper with an adhesive back. Cut donuts to fit over the axle faces. Clean the axle faces with acetone (not nail polish remover) to get a clean surface for good adhesion. press the sandpaper in place on the axle.
Now when the QR is clamped tightly the grit will bite into the inside of the dropout providing tons of holding power at reasonable clamping pressure.
As an alternate to the sandpaper, you can use beach sand, or commercial grit, and adhere it to the axle with nail polish or paint. This works best if you mix the grit into the paint and paint them on to a clean (acetone) axle face.
BTW- just in case, and please don't take offense, but are the QR springs on with the small end of the cones pointing in toward each other?
Now this I didn't know and you're suggestions sounds great. Yes, the springs are on correctly. I'll try the new caps (and likely use some sandpaper too until the paranoria goes away).
