How long does it take for lubricants to kill a primer

[Jack B.]

Don't really know , guess you've got to be careful with lubricants and use them as sparingly as possible. Like all oils a little goes a long way. Never had a misfire happen to me in 45 years reloading. Guess I've been lucky.

I looked around and tried to find the writeup I remember of the oil soaked primers still working but could not find it. I'm certain I did not imagine it but I don't remember the details of what primers they were. Certainly different brands of primers will be more susceptible to oil contamination than others.

Didn't Box o Truth do a test like this a few years ago?
Sir, thank you for your sharing, good luck with that surgery!

I agree with Jack B. be careful how much and where you put lubricants. Just rememberd my buddy who was head armorer with US Secret Service was testing lubricants and he said it was amazing how some lubricants put in one place was somewhere else the next day due to migration of the lubricant.

I have been reading about the Q Max products and they make so many I can't figure out which one to try first. I am primarily interested in long term storage in a high humidity climate.

Since this was live ammo are you sure the oils did not harm the powder? Powder is a lot easier to impact than primers. With crimped bullets and primers the primers nor the bullet would move if the primer did go off on rifle ammo. It may on handgun, just depends on the volume.

Chances are good some of the oil went past the primers but oil was only applied once where water was more often as it dried up with an hour or so of wetting the ammo down. None of the oil dried up.
Off hand I would say the amount of oil was enough to kill a primer but not so much as to coat all the propellant.

Thanks for this wonderful information.
What about shotgun primers those are lacquered on the inside / flash hole?
Not sure how resistant they are to oils but the lacquer in some seems pretty tough.
Some have been "aging" in the basement for 30 years and still work like day one.

Did not see that?????

BoomBoom, I make up Ed's Red with only mercon dexron, mineral spirits, K1 Kerosene (hard to find) or off road diesel fuel.

Higgite,
Got a good friend who was head of the military match ammo facility. At the beginning of the season he called primer manufacture (won't say the name) and wanted one tray of every lot of large rifle match primers they had with over 80,000 in stock.

When he got them he went out and ran their known match loads on the FA Mount and through the crony and he said the difference in primer lots were amazing. He then ordered 80,000 of the best primers they were running that year.

Bottom line is imagine the variation you can get with marginal striker velocity/energy and couple that with so so primers and you have a formula for seeing your name way down on the score sheet ! ! ! ! ! !!

Thanks. I forgot which thread I asked you that question about. I always learn something from your posts--thanks for sharing.
