Be carefull with WD-40, I heard that it crawls up in between the case and primer and neutralises the primer.

Yup, the box of truth website did tests on oils and what they do to primers.

Don't count on WD-40 killing primers. I read a test done several years ago where the guy soaked primers in WD-40 then let them dry for a week. Then loaded them in cases with powder and bullets. All but one fired. Primers are tougher then you think.

I saw that one too, Bushmaster. I think water was shown to be more of a problem than any of the oils they tested. What I want to know is why handling primers causes so much of a problem with misfires. I used to use the included ram primer on my RockCrusher press to seat primers and had to pick up each primer to place it and had a lot of fail to fire rounds. when I switch to the hand primer and never touched another primer the problem was solved. I just figured that the oils or moisture from my hands was the reason but I never did figure out a cure - othr than using the hand priming tool.

Not sure how long ago that was paul. Modern primers have a lacquer sealer to protect them.

Several of Lee's presses use a single priming system that requires you to hand feed each one. Not heard any problems with them except a lot of "dropped primers" (as in on the floor).

I've been using Lee's Auto Prime II from the beginning (27 years now) with no problems whatsoever.

Yep, The Autoprime from Lee and the RCBS hand primer both do a very good job. I haven't had any fail to fire since I started using them.
As for how long ago.... well it was in 1970 or a bit before and I know that winchester primes of that time had the "sealed" primer material - they were designed that way so that the ballpowders would not get into the primer and cause irregularities in the firing sequence (blow the gun up). I even went to using a set of tweezers so I didn't "touch" the primers before I finally got the hand primer and never had to touch another primer.

I spent many days hunting coyote in North Dakota in -20 degree weather and freezing wind 30 some years ago. There was only two things we found worked. Dry graphite is one but gets all over your gloves and clothing and everything it touches. The other and my favorite to this day, Tri-Flow. It is a great oil penetrant and it doesn't get gummy. Leaves only a dry teflon coating. Suppose to have superior lubricating qualities.
Google it. Can find it at the local hardware store.
