Here I am putting the oils on the primers.

Here's how they looked with the oils puddled on the primers.

And here.

After I puddled the WD-40 on the primers, Tman said, "Someone will say that if the WD-40 was sprayed with an aerosol can, it would make a difference."

So, I set up another set of cartridges and sprayed them with WD-40 out of an aerosol can.

Now everybody will be happy.

I decided to test them as follows:

I will shoot one round of each group, each week, for 5 weeks.
Then 5 shots each on the 6th week.

We would look for failures to fire or "weak" shots as evidence of primer deterioration.

Week One:
After one week, the rounds still had puddles of oil on the primers.

It was interesting that the Hoppe's #9 had turned the brass green.

Pretty neat, isn't it?
