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.
