Lead free primer question

Post by prc-104 » 08 May 2013, 07:09

Back when the SS195 started getting those lead free primers, Way I look at it is a shiny silver looking primer, I read stories.
I stopped using ss195 other than for practice.
Now I see the AE5728A rounds and they have the shiny silver primers.

So I asked my supplier and he says the AE5728A have leadfree primers but I shouldn't worry about them going bad.

Fill me in all you guru's. What's the story on these green primers?

Thanks,
John

They only have LF primers if the box states. the new SS197SR LF has LF primers and the 195LF and 198LF have LF primers. The AE is not lead free.

The new 197SR LF primers are black/gray.

The AE5728A has a lead warning disclaimer on it so I am thinking they are not Lead Free

Better use those LF primers, they're only good for about six months

Also the 'green' primers have a sealant because to reach the armor piercing hyper velocities they require a higher pressure so the primer needs to be glued in.

The story actually is,

People are too lazy to use the search function.

haha, kidding aside,

they are the same as the other LF primers. Keep them in a respectful environment that is free from hazards that you normally keep your guns out of; moisture, sand, grime, grease, etc.

and they will in turn, serve you well.

I have yet to hear a report of anyone actually claiming a failure of a LF primer.

Last week I went out to the desert with a couple of guns and a lot of ammo. I had two ammo cans of gun show 9mm. Both several years old. One had silver colored primers and were sold to me as "factory reload". The other were brass colored primers and were sold to me as "hot Israeli surplus". Every one of the brass colored primers failed. Solid firing pin divot, no bang. The factory reload stuff worked great.

I have had failures of the older LF. The newer LF are getting better and shelf life is something the primer manufactures are still working to improve.

Brass or nickel plated does not really mean anything when it comes to being LF or not.

Now some manufactures will black nickel their primer cups to so they are LF primers.

GONRA assumes DDNP is the explosive ingredient in these lead free primers (may NOT be of course!)
Decades back Japanese Blasting Cap Industry really studied DDNP.
Copper is really Bad News for DDNP shelf life, even for blasting caps.
(Blasting caps don't have to have the looong shelf life expected for ammunition primers.)

Thus, no bare copper or brass primer cups for DDNP type lead free primers.
Aluminum (probably too soft) and zinc plated brass / steel cups are OK however.

By this time, should be a lot more knowledge on all this, hence the various colored primer cups.....
