Good info but I've only had one revolver that took #11 caps. All the rest took #10 except for one old one that takes #9 which they don't make anymore.

Ooops! Sorry . . . I misunderstood what this post was about! :D

What's this accusin' me of tellin' all yer secrets and you up and tell on yourself!?!? :D

Great info sharing. The first time I saw nipples like that was a fellow cowboy action shooter (my friendly competition) who did that to his Ruger Old Army so as to get a lighter hammer pull for faster shooting. Accuracy not being the game in CAS so much as speed and merely making hits on steel.

Long, short, skinny or fat. It's a matter of taste....

I have never seen that treatment for nipples.
Don't know if it is good or bad. But, if it works for you that is all that counts.
I miss Friendship. Used to live right up the road and spent every weekend at the range with friends. Haven't been there in many years. Miss it.
Good shooting.

I've opened mine up to around .050-.060", then ran an 82ยบ countersink into the powder side to improve flame out. Seems to work pretty well. The only problem I've really had with regular BP nipples concerning cap fit are those longer "flame thrower" jobs. All in all, I love all kinds of nipples as well.;)

Be good to them, they'll be good to you:D

Wouldn't that cause excessive hammer blowback even with a Remington Mainspring?
It's kinda the opposite of Treso, hotshot, Uncle Mikes or Spitfire type nipples?
So that's why I'm askin'... :confused:

SG - are you replying to a7mmnut or [email protected]?

a7mmnut says he drills them out to .060" - I assume he's talking about the flash channel - which would certainly be the opposite of the Treso design.

But [email protected] leaves the flash channel narrow and only opens up the tip. He's taking advantage of the Treso design and improving it by creating a smaller impact area on the tip of the cone. That smaller impact area results in significantly higher impact pressure on the explosive cap material.

Leaving the flash channel narrow like the original design preserves the best feature of the Treso nipples in that it lessens blowback force on the hammer and improves flow of the hot gasses into the combustion chamber.

That is excatly right Mykeal!!!!

I like the idea, but only on Ampco brass nipples.

Drilling out the nipple cone does result in significantly higher impact force on the explosive material, so reliability should be very high. The down side is that the strain on the nipple tip material is also much greater (same force over smaller area = higher strain), and they'll mushroom much faster. The Ampco material is very resistant to plastic deformation and so should last substantially longer than stainless steel or OEM steel.

To allow for this, my mainspring in my Rem. is very light.
