Will Dillon case lube kill primer or powder?

I'm reloading 45ACP now.  Citric acid cleans the brass, then rinsed in distilled water, then dried.  Final step is tumbling in walnut media with Dillon Case Lube.  I like the smoother resizing it affords, even in a carbide lined die.

So far so good, but in storage, will the Lanolin in the lube act on the powder or primer & eventually neutralize it, like petroleum products would?

Short answer is no, assuming that your aren't leaving wet droplets in the case.
I spray Dillon case lube (sparingly) directly on the brass in the hopper and have not had any issues with proper storage.

Hope that helps

Dillon case lube will not adversely affect either powder or primers.

Well, as mentioned case lube will kill the gun powder if the lube is wet when it makes contact with the powder.

I used to throw my shell casings in a plastic bag, give them a few pumps of case lube, roll them around and then start loading. Some casings would then unintentional be laced on the inside with case lube and when I loaded them some rounds would be affected. You would notice it that some rounds would be significantly weaker than normal. Typicaly doing about half the muzzle velocity of a normal round. Took me quite some time to figure this one out. Thought that it was something wrong with my machine.

Now a days I lay them flat in a box and spray them from above. And giving the lube some time to dry before starting to load.

Agree with first comment

I had a couple of "Poof" loads at the range today. Out of 100 rounds of 9mm, 2 of them had just enough power for the bullet to leave the barrell. I had sprayed the cases and they were still wet when I started loading then. The powder must have been contaminated and I am lucky I did not end up with squib load. I spray my cases with Dillon Lube and the reloading process goes a lot smoother. I am going to let them dry at least 5-10 minutes. Better yet, I think I will spray some in advance and store them for the next loading session, once the lube is on the cases it is there forever. I tumble my loaded ammo that has been lubed for 15 minutes to clean them up.

This reply is to the Dillon administrator who replied up thread. So just to be clear I am reloading 45-70 and I put the cases in a block case mouth up and spray with Dillon case lube from all 4 sides. When I drop my powder I see powder stuck to the inside of the case in the top half of the case, a lot of powder. When I seat the bullet it is going to have to squeegee the powder as it goes in. You are saying this will not affect the powder and it will fire just fine? As I wrote this I thought to myself hmmm maybe I should put the cases in the block mouth down and then spray.
