S-7 is an air or oil hardening tool steel that is characterized by very high impact toughness. The combination of strength and high toughness makes S-7 tool steel a candidate for a wide variety of tooling applications.
Lehigh Defense is now offering a replacement #11 Nipple for muzzleloaders. The metal used to create this new offering is the harder S-7 steel. The product is also undergone Heat Treating to make it even more durable. At this time the nipple is only available in 1/4x28 thread configuration.
When I first heard about this product, I was really wondering why? After a conversation with the folks at Lehigh - their goal was to create a stronger more durable, longer lasting product. S-7 is certainly a place to start, much better durability than steel or 416 stainless steel.
I have this thing!!!! I want a nipple that with a #11 cap or even a RWS 1075 cap on the nipple post, it will not fall off and it becomes water proof! When a nipple is pressed on to this nipple with a capper or even pushed with your fingers it will stretch the convolutions to the point of flattening the leading edge and not allow water/moisture a pathway to the ignition material in the top of the cap.
It does create a problem for some users in that if the unfired cap is pushed on tightly you will not be able to remove it with your fingers. Most often it will need to be peeled off the post.
The pictures I am posting are from my testing for water proofing

After, I peeled the submerged caps off the nipple post, I did take a Knight DISC out to the shop place the nipples back on the nipple and test fired them. Both the CCI #11 mag and the RWS Dynamit Noble 1075+ ignited with out a problem. Further I shot 3 ea. of both caps on the new nipple installed in the DISC.

im more interested in how well they flow and set off the subs.
Hoping to find out tomorrow! I am hoping to run out the farm with a DISC and get some shooting in.
This should tell you something

was going to order one but i see they only have a 1/4x28 listed? Any plans on a 6-1mm?
I really do not know right at the moment - but I think they are in the plans. I thought they were or have, I think they also built CVA breech Plugs.
Go to this link and ask about CVA products...
