Platinum lined nipple
« on: September 15, 2008, 07:11:51 PM »
I thought that I would take a picture of this nipple for those who may have never seen one.  This nipple came from a London shotgun but they are most frequently encountered on long range Match Rifles.  The protection of the platinum makes the nipple virtually impervious to erosion from breech gasses.  Shooters of the long range rifles say that as few as 10 shots can burn out a conventional steel nipple thus effecting accuracy

Even that has its restrictions.  A number of LR shooters have gone to Swiss 3F and reports are coming in that it is burning out platinum nipples.  Historically, most shooters used 1.5Fg.  The guns are also unique in that the flash channel is not wide open, but rather the nipple seats on a flat seat inside the channel that has a small hole in it.

Interesting specimen.  I've never seen one with a slot instead of a hole.

I use to make some platinum nipples . The cost of even platinum scrap has gone thru the roof , so i only make them for me any more . At $200 to $300 worth of platinum in a nipple don't throw one away if you think it is worn out !

Sam,
1/4x28 platinum lined nipples are currently priced at $85.
However, the one shown in the picture has about 3 times more platinum than is used today to make them.

Yes i should have said old platinum nipples. I bought 4 old nipples last year at a gun show in Charlotte for 10 bucks each . I got $1050 for the platinum. I thought they where 1/4 or 12 thread, but they where metric so i took out the platinum .

I had an antique platinum nipple in my deer rifle, thought the plug had dropped out but I just had a look and it's still there, must have dreamed it  ::)

OTOH the gold seal around the plug is eroding, sounds like it will be an expensive shot when I eventually launch it down the 100 yard range  ;D

It has a round hole rather than a slot though.

This is bad news  :o

A shotgun I just bought is worth more in platinum content than I paid for it  :o

Are we going to see irreplaceable antiques broken down for scrap?

Bill Roberts used to make platinum lined nipples, he used old jet aircraft ignitors as the source of platinum.  Could be that the cost of even scrap now makes them to expensive.
Robin has hit on an interesting point, hopefully the scrap seekers will only choose guns next to the junk pile.

Rick Weber is making most of them for the LR group now.  Joe Hepsworth also sells them, but I don't know who makes his.

I tried to encourage some experimenter to try making a couple using platinum tipped auto spark plug electrodes but no one ever did.  I was curious how they might work.

Joe Hepsworth is making his own. Don't know what he gets for them but he uses them himself, pretty good endorsement.

I have a question ? A lady friend of mine , well thats all i will say about her , just gave me 2 platinum wedding bands of her and her ex. I would say they are the same type platinum that i have bought from Swest. Would any one know ? If so i might have enough to use in a couple of nipples i need to make.

I just ran across this link stored on one of my old computers.  Everything you'd want to know about platinum and old guns.
