#10 is smaller, and will not usually fit on a #11 size nipple. However, a #11 cap can be pinched to make it a tight fit on a #10 size nipple. Best plan is to use the appropriate cap for your particular gun.

You can swap out the nipple and it will work fine.

in other words they will both work!! but a MUSKET CAP WILL NOT!

I use 10 on my pistols and my CVA hawken manual said it was an 11, but 10's work on it and I ahve to pinch 11's to stay on during the hunt. Missed an 8 point one time when one fell of and I did not know.

Best bet is to try various brands and sizes of caps. You can use a loose fitting cap if you just squeeze the open end a LITTLE BIT, making it a bit oblong and sliding it on the nipple. Different nipples and different size caps fit differently. Use Nev'r Seize on the nipples and don't tighten excessively, just snug.

If I can find a link I came across a page once that had the measurements of CCI and Remington caps and why a #11 in one may fit better than the other.
