Title: Whats the difference?
Post by: vthompson on February 25, 2010, 07:41:45 PM

Hey guy's, I seen this question on another forum and nobody seemed to have a good answer so I thought that I would see what you all had to say about it so here goes.

What is the difference between a #10 and a #11 cap for percussion firearms?

Thanks for your time.

The diameter of the cap.  The #10 is smaller.  it seems like RWS used to give the diameter of their caps, but not so positive.  Good thing to look up, for those that are inclined to do research.

Got this from some other sight that I've long forgotten.

Rem #10, Rem #11, Cci #10, Cci #11, Rws1075

Bottom line, 10's are supposed to be smaller than 11's but caps vary by manufacturer. Once you find one that fits the nipples you use, stick with it.

From what I think I've seen, Remington seems to use a softer material, or they have larger pleats, or something. It seems that they can be stretched down further than CCI.
I could just be dreaming this, but that's OK.

In my experience, there's more difference between lots of the same maker's caps than in that maker's sizes.  This holds when comparing differing manufacturers as well.  

To put it succinctly:  It's a crap shoot.

It only gets better when comparing nipple sizes and profiles.  

When I first started in Muzzleloader shooting, there was a discount chain called "Jafco" based in Seattle.  Just before they went belly-up in about 1980, they had a big sale to get rid of all their shooting stuff.  I bought two bricks of percussion caps, one Remington and one CCI.  Both #10's and both noticeably different in inside diameter and depth. Due to a pricing SNAFU I got them both for $1.29 for a brick of 1000. I called it to the manager's attention and he said it was too much hassle to straighten it out so,  "Good Shooting".   Both were darn good caps, too.  I'm now working on another brick of CCI caps, of current production.   They're good stuff, too.

IMHO caps is caps and if they make the powder go boom without noticeable delay at the first hammer-fall I am happy.I did get a couple thousand navy arms caps some years ago and they were excellent I have not seen them again.I have used 10s on a rifle just filed the nipple in a drill press,did the same thing to use RWS. I agree the quality control has suffered with variation in the same mfg's caps.Now it seems that 10s are easy to get 11s a little more difficult and getting pricier all the time.Back to rock locks I guess.

Also, #10 caps are commonly used on perc. revolvers while #11 are for single shots and rifles!
