Your heading, "flirting with the grim reaper" might be a tad over dramatic.
Anyway, since I don't do much of anything like everyone else, here is what I do.
After I blow out the case in a .269 neck 6PPC Chamber, I place some sizing wax on the turners mandrel, and simply press, (using a little Sinclair Arbor Press), the case onto the neck turning mandrel untill it contacts the tool.I then clamp the T-Handle one, and turn the neck. It turns out that the ID of the neck of the case is just about the right size when fired in a .269 neck chamber.
As you press it on, you will feel where it hits that tight spot at the neck shoulder junction. No big deal.
Keep in mind, I do not turn necks by hand very often. I have a little neck turner on my desk, and if I want to make up 10 or so new cases to take to the range for practice, I do it. I can blow them out, trim them, and neck turn all right there.
Any large quantity and I set my lathe up and single point them.
Gary Walters does the same thing with a .270 neck......jackie
