The .006" depth I quoted is an industry spec that was given in a technical article by Shooting Times in the late 80s. Not an arbitrary assumption or blank statement.
Hi,
Yet during many of those same intervening years, Forster has suggested 0.004" was ideal.
So I'm not gonna argue that a particular depth is best. I'm just a beginner at this hobby: didn't get started until Santa was good to me at Christmas--in 1965--and I still learn something new every time I sit down at the bench.
One thing I've learned so far is that neither primers, firing pins nor I are as smart as the engineers! Primers know only that they have to be hit "so hard" to go off. Firing pins only know that they can't hit "so hard" unless there's appropriate resistance to their strike. And I only know that the way I can ensure these two items get what they need is to make sure the primer's seated to the bottom of the pocket. I use one of two Lee Auto Prime tools that are kept well lubed, away from any 800 lb gorillas, and they've done that job for quite a number of years. The one set up for large primers is old enough it didn't even come with a primer tray... it's a "single shot."
Now, one of the great things about reloading is there are many ways around the barn that all end up with us in the same place. So if my way works for me, yours for you, and they're different, so be it! No harm, no foul...
