Knight Red Hot Nipples - Correct cap Fit
 

For the past month I have recommended the TRESO nipple in a #11 configuration...

Recently I found a source for the TRESO AMPCO nipple - this is a get nipple EXCEPT for one thing. The 'flash hole' is drilled to .028/29 which is great for the ignition of real BP or the Pyros - but I use T7 which takes more heat to ignite in really cold weather. To cure this problem I order these nipples from Buffalo Arms in Ponderay, ID. When I get the nipples I then drill the flash hole out to .031 - That works perfect even sub-zero weather. Here is a link

The nipple in the center is the 1/4x28 Nipple




This is proving to be incorrect. I just recieved 3 new ones and tried them for fit. The nipple stack is to small to get a seal with a #11 cap.

So this point I am back to the RST-S - stainless steel! Probably another reason Track of the Wolf stopped carrying them.

The nipple works well for ignition - but not seal....

I had that problem. I haven't drilled them yet but I did address the loose fit of the nipple.

I just drilled mine to match the TC Hot Shot. They are .035 so I drilled the Ampco nipples out to .035

Jeez Ron that is way above what I normally drill. I have always used .031 and most often toss the nipple when it gets to .035. That just allows to much blowback pressure for me - but I am using T7 also which just naturally creates more pressure.

I see and understand how you are creating a wider/ greater diameter nipple stack. And certainly that will work with sidehammers and percussion hammer guns. But for me since I shoot mostly bolt guns that would move the nipple to far from the face of the bolt and the hammer/firing pin most likely would not reach the cap with out shimming the nipple or breech plug. Yet on the other hand I could also cut another breech plug to be greater in length.

A few years back when I was buying the AMPCO nipples from Track of the Wolf they were perfect other than the size of the flash hole. TOW stopped carrying the AMPCO and made a copy of that nipple and designated it as a RST-S. This nipple works very well and comes with a .030/31 flash hole.

The big reason that I prefer the nipple stack to be larger in diameter is when I push/place the cap on the nipple I want it to fit tight enough that it actually stretches the convolution in the cap to almost flat on the bottom edge of the cap. This stretching works to make the cap water tight. I really do not have to worry about rain and/or snow getting in the cap or the breech.

I was really hoping that the TRESO would fill the need the way the original AMPCO did. TRESO uses the AMPCO metal process which is really good but does not match the size of the AMPCO. Part of this may be that some people were complaining that could not get the cap off the nipple post without shooting it off or peeling it off. I do not think they recognized the value of the nipple to nipple post seal.

Hope some of this makes sense...

Like I said Hot Shot is at .035 so that is what I took them too. I normally discard at .038 for my guns. At .035 the hammer will not cock. At .038 it will that is what I base my numbers on. I got a platinum lined nipple and it was .028 and I could not get the P to go regularly.
The fatter diameter is a benefit to keeping out moisture. I hunted this year for 8 days is snow and rain. I was using a cows knee and a piece of electrical tape over the muzzle but the gun went off perfectly when it needed to. The tight nipple and cap fit has to only help.

The Ampco nipple is .632 after adjusting it. A standard TC nipple is .550 A TC hot shot is .585
I have some track of the wolf "hot-shot-RST" They are .634
The difference between the Adjusted Ampco and the RST is .002 Are you sure that is a problem?

I understand that - doesn't the Hot Shot also have small vent hole near the top of the nipple stack? The Hot Shots that I had had that vent which relieved pressure somewhat.

Same for me I could not get even T7-3F to always go off in sub-zero or close to sub weather. At .031 all works well and I keep more pressure headed up the barrel versus coming back. Sometime if you get a chance try a .031...

Exactly!

This is the nipple fit I need when shooting a bolt Knight Western Rifle. As you look at this picture I would actually like the top of the cap to be even closer to the face of the bolt.



This picture is much closer to what I would like to have... This is with a Knight HOT Shot in the rifle 0 CRAP! Knights are not Hot Shot - they Red HOT's



That is an Original AMPCO in the rifle and if I shortened it the firing pin would not reach the cap. And this AMPCO is slightly less the Knight Hot Shot and if I remember correctly the TRESO is .018 shorter than the AMPCO


In our application for the Knight yes, that would be a problem - Remember Knight cuts the breech plug to fit their Red Hot Nipple which is different than the TC. The TC is shorter.

A friend of mine in up state Washington just got a new Ultra-Lite and ordered a couple of TRESO's he could not reach them - but his rifle functions great with the stock Knight Hot Shot. A little difference makes a big difference in this application. In your side hammers and the MK's no big deal at all.

Do you know what the length of the Knight nipple is?

The TC Hot Shot doesn't have the small hole on top. At least mine don't. The TOTW hot shots have the hole on top.

Right now - no I don't - but I have it written down someplace... Found it .645

This is the TC Hot Shot I use to have for my Renegades

Sabotloader, You might give the MSM Spitfire nipples a try if overall length is what you are looking for? They are the longest nipple i have ever seen, (I wish i had measured it) I found 1 for my Lyman Great Plains Hunter rifle, that nipple was long enough that my rifle would not go to half cock. I target shot the nipple and i wasn't impressed with durability, I started a thread about them on Castboolits way back and most folks swore by them being tough, maybe i got a bad one? My absolute favorite nipple is the Treso Ampco nipples from Buffalo Arms, they are TOUGH and hold up extremely well

A Knight Change - maybe
 

Well Darn! After all of this... I made a phone call to Knight

The new Knight Red Hot nipples #M900013 have been changed to give a positive seal on #11 caps - including the RWS 1075+. I suggested this several years ago when I first started using AMPCO's - even sent them a demonstration. Well apparently or maybe something positive may have happened. I ordered 4 of them when they get here I will test and post...

54 - I just called October Country in Hayden, ID - talked to the people and I have ordered one for testing purposes. I have never had one of these that I know of...

Thanks - I will let you all know

For any of that still might be following this topic... Another test nipple arrived today.

It is another TRESO but it is for the Colt Walker Pistol

It measures the same length as the TC TRESO .637



The RWS 1075+ does fit a little more snug like what I am looking for but in my mind not enough to serve the purpose...

More #11's arriving later....

MSM - #11 Nipple
 

Yesterday I ordered another test nipple from October Country Muzzeloading here in Idaho...

http://www.octobercountry.com/



This hardened Stainless Steel nipple was suggested by another forum member 54bore on another site.

Today the nipple arrived - I got to say I open the package not expecting it to work - BUT!!! It is an excellent fit!



The cap is tight and will be water proof

The nipple is longer than a stock Knight measuring .678 - which is long as compared to a stock Knight nipple

Flash Hole - the hole is small .028/29 and I will need to drill it out to .031

Again the down side is to get the nipple off the post you will need to shoot it off or peel it off with the edge of a knife....

The next step is to install it in DISC and see if the hammer/firing pin can hit the cap hard enough to drive it to ignition...

Still have some new Knight Red Hots coming for evaluation...

I just feel good finding one that works the way I prefer - thanks 52!

This afternoon the new Knight Red Hot #11 nipples arrived in the mail today.

My curiosity took over and I decided to put them to the test...

With a capper I applied the RWS 1075+ cap on the nipple. Then tried to take it off with my fingers - didn't happen

The picture(s) hopefully will explain what I was testing for.



The flash hole is the correct size .031/32 - no drilling needed.

I think the search is over and the shooting/hunting can commence...

I will add a more information that I just found out about the Red Hots... They are hardened to a ridiculously hard number - something like Doc White use to do to improve life of his nipple/breech plug combination - so they really should be a lasting product...

With this last bit of information - I think I am even more satisfied with the new Red Hots... Now lets just hope Knight doesn't change contractors again... no wait!!! if I ordered enough of them now I would have to worry about it!

Sabotloader, how does the redhot fit the other #11 caps than the RWS? I'm using winchester which I believe are the same as CCI.

Yes the CCI's fit very well although I did not give them the bath test...
