Are the bullets seated long? Do they engage the rifling? Are there rifling marks on the bullets that did not fire?
That will cause a primer not to fire.
Suther the fact that another loader also had ignition problems definitely points to the tool being out of adjustment and the primers not being seated. I have fired 1000s of rounds without cleaning pockets and have never once experienced a misfire because of it. Either try to adjust your priming tool or throw that LEE POS in the garbage and buy yourself an RCBS bench mounted priming tool like I have used for 40 years............can't beat it and it never wears out and you can seat primers .005" below grade if you want to with this tool. I have even found that I can apply enough pressure to expand the primer enough to keep it from falling out of a slightly over used primer pocket.........for that one more firing. I have actually be amazed over the years at how much abuse and deformation a primer can sustain and still go bang, the only thing they will not tolerate is not having a solid backing to allow the anvil and firing pin to do their job.
It has been proven many times that the new sealed primers cannot be contaminated with finger oils or even submerged in oils for days. There was a thread here about a year ago disproving the oil contamination theory completely.
How can a bullet seated long and into the rifling cause the primer not to go off? I would have thought if anything it would help hold it to the bolt face.
I do not mean to be rude but are you sure you put powder in? I have made that mistake more than once. Or at least that was my verdict when I had the same issue with 30-06 and 303
Primers are fussy. Something as simple as sweat/oil off your hand can make them inert. Brass lube has accounted for many dead primers.
When you get a chance pull a bullet and dump the powder and see if the primer had gone off.
Usually if you forget the powder the bullet doesn't budge, and there isn't the slightest sound. Pull the bullet and its baked black on the base and that's it.
I was wrong.
Put 10 Winchester small pistol primers in a fired shot shell, added some water and shook for 15 seconds. Dumped the water, added some CLP and shook. Then dumped primers on paper towel and loaded in 9mm cases and fired in a Glock. Not one bang.
I should try again with water only.

I doubt this. Take some primers, rinse them under the tap and then spay with some lube -then seat them and fire in the gun (no powder or bullet) They will probably all go bang.
I will do this tonight and report. Some other guys can do the same and report here. maybe I am wrong....
