This new is made from s7 tool steel and is a very tough metal. In the previous post I mistakenly labeled it as 17-4 Stainless

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.
Today project was to test fire the new Nipple with a BP sub powder.
The nipple performed really well and it was fun to shoot with it. But... If you have seen the previous post:
https://hunting-washington.com/smf/index.php/topic,239788.0.html
In that post I showed how tight the CCI #11 and RWS 1078+ caps fit the nipple post - providing a water tight seal between the post and cap. There can be a negative side to this tight fit also. Anybody that shoots caps understands how dirty the Nipple and the Breech becomes. I found that after 5/8 shots with a Magnum caps the nipple post became so dirty the cap may not seat on the post correctly. Wiping the post with a damp patch cleared the problem very easily.
Here are a couple of composites of the shoot this morning....

I am really looking forward to this fall's hunting! I am going to take on a new hunting "student". My last one is up and taking deer with little to no help from me at this point.

Awesome, Sabot. Thanks for sharing. I also have to clean that post in either the Bighorn or the Mountaineer, but especially in the Mountaineer (I think the confined space in the breech means that the fouling is more concentrated).
See that would make good sense!

Very neat! It is always good to get a new shooter started off with an experienced mentor!
