Guys, The primers have a very significant dent .... plenty deep enough for detonation. When primers don't ignite, the powder charge, bullet seating depth, or many of the other things listed as a potential problem just don't matter. Also if primers were not seated properly, there wouldn't be such a deep firing pin dent.

I'll stick with my "cleaning fluids in the primer" analysis.

I use a dry tumbler, but still this is the way to go.

I've got two tumblers, and a sonic cleaner, I've tried using the sonic cleaner however inevitably found small amounts of liquid inside the case, even after letting them sit for quite a while in the oven (really torqued my wife). Since that time I've always used my two tumblers and never have had a problem. Will use the sonic cleaner by "Harbor Freight" to clean jewelry only.

Incidentally I use a real finely crushed walnut, with just a little car polish put in to clean my brass where it looks like new, this is after de-priming the cases naturally. BTW I've got several 5 gallon buckets so the dust and mess are of little consequence, using a couple of colanders to sift the walnut media back into the 5 gallon buckets. Note: I haven't found any difference in using bright and shiny brass as well as tarnished brass when developing a load, the secret is cleaning the primer pocket, and when doing rifle casings making sure the COAL is correct and the face is square.

I never thought it was the primer's fault -- just raised the question in my original post to be thorough..my primers are about in the right place and pretty uniformly seated by the Dillon..

As Iowegan surmised, I am satisfied that the answer lies in the ultrasonic cleaning regime I was following...I loaded and shot 80 rounds yesterday with brass I knew to be dry and all of them ran very well..

My Lyman 1200 vibratory cleaner was sitting in a garage 200 miles north of me when I got my Dillon and rather than make the round trip so I could begin loading I bought the Harbor Freight 2.5 liter ultrasonic cleaner...and it does a fine job both inside and out. I am shooting at a nearby public indoor range and the brass I pick up is quite grimy from the usual junk on the floor...it's gotta be cleaned somehow before going near the dies.

But now that I know the pitfalls of the remnant water I'll be a little choosier on what I use ultrasonic cleaning for.

One member asked if I was using a light load -- details are in the first post: 4.9 grains of Tite Group, which is .1 grain above the minimum Hodgdon reloading web site recommendation. Any thought that I should go heavier?

The round I was shooting (200 Wilson Combat LSWC, Fed 150 LP primer, 4.9 grains of Tite Group, 1.25" COL, .469" crimp) chrono'd at 793 fps (average/13 shots) out of my Commander's 4.25" barrel.

Interesting: The same load but with a CCI LP primer chrono'd at average of 855 fps (average/13 shots.) I am shooting the Fed 150 primer but am wondering if the extra oomph netted by the CCI primer is consistent with the group's experience? And is it desirable at those velocities?
