I just purchased and new army 58 brass frame. This is my first black powder pistol. i have fired others but this is the first of my own. The problem i have is i cant find in the manual what size caps. Do i use #10 or #11? i really want to get outside and fire ths gun.:banghead::banghead:

11's should work fine.

CCI 11's fit a tad tighter than the Remington's. Remington #10's fit well on the Colt 1860 revolvers.

[husker]

#10 is what your looking for #11 are to big for my pitta new army.

[bigjohn78]

Can anyone tell me the differance

[husker]

as far as i now just size the 10 is smaller in diameter than the 11

[husker]

my rifles take 11 and my 2 revolvers take 10

[bigjohn78]

I bought both. The only differance i see it the #10 are longer. both fit on my nipples

[husker]

i stand corrected. sorry

[Sagetown]

bigjohn78 that's good to hear. I wasn't sure if the new army had larger cap nipples than the colt. When using the #10's just be sure they seat all the way down on the nipples.

Actually the 'right size' cap is a crap shoot.

There is no relationship between one brand of No. 10's and another brand of No. 10's. There's also no relationship between No. 10's and No. 11's within a brand.

Here are some measurements I made. These numbers are the average of at least 20 samples of each brand and size shown. 'Size' is a function of the diameter of the opening and the height, because the nipple is a cone shape.

Three notes: first, the measurement of the opening is very difficult to make with calipers, so the error on those numbers is probably about .002 to .004.
Second, these measurements vary by batch as well; the box you buy today may well be different from the box you buy next year.
Third, you don't get three decimal precision manufacturing for 4 cents, which is what caps cost. Don't expect too much.

Also, nipples vary as well - they cost more than 4 cents, but the precision is about the same, so when you change nipples you start all over. And the nipples on some other guy's gun may be slightly different than yours even if it's the same brand and model of gun.

Bottom line is that no matter what someone else says he uses on the same brand and/or model of gun, the caps you buy and the nipples on your gun may be entirely different, so it's possible you would have to spend about $20 to find the 'right' caps.

mykeal; I noticed your chart shows the Rem #10's a little wider than the #11's.
Yet the #10's fit much tighter on my gun than do the #11's. Just comparing.

[whosyrdaddy]

Rem #10 nipples are considerably longer than Rem #11 nipples. Therefore, they extend farther down the tapered nipple making them feel "tighter".

You need to read the notes below the chart. The chart shows a difference of .001" between the Remington No. 10's and No. 11's, and the first note below the chart states that there is a substantial error in the measurement of the opening diameter, as much as .004". That makes the .001" difference meaningless; it's entirely possible that the No. 10's average 0.163" across while the No. 11's average 0.170" across!

But whosyrdaddy identifies the real reason. Since the nipple shape is a cone and the No. 11 is shorter, it 'bottoms out' before the sides get tight, while the sides of the No. 10 get tight against the cone before the top bottoms out.

Remington # 10 `s will fit the Pietta made brass frame Remington like a glove ...try them you`ll be glad ya did .

I did, but whosyrdaddy really hit the nail on the head with his post: Rem #10 nipples are considerably longer than Rem #11 nipples. Therefore, they extend farther down the tapered nipple making them feel "tighter". just as you stated:But whosyrdaddy identifies the real reason.

Has anyone ever seen an actual gun that was abused/used with large charges to the point the frame was damaged/stretched on a brass-framed remington?I know use mild to moderate loads and they will last a lifetime.

[mykeal]

Yes, four or five over the last 30 years (none of them mine). There is an excellent picture of a recoil shield with the imprint of the back of the cylinder in it that occasionally shows up on the revolver forums.

I have a 1858 Remington ,all steel 5 1/2 inch barrel and am using CCI #10 caps that fit just fine. :)

I just recieved a 1851 round barrel Confederate Navy in blue and brass frame. Both from Cabela's within the last two weeks.

I have fired the Remington with 30 grains of Pyrodex P powder and it is SWEET!! No problems with ignition or function.

Put a big grin on my face with all that flash and bang!:D

The 1851 instruction book from Cabela's says to stay at 25 grains max with black powder. Pyrodex and 777 have greater pressures and need about a 15% reduction in powder.

Brass frame should be ok if you keep your loads sensible and if you don't try to "Dirty Harry" your pistol.

I think the Remington in steel can handle a little hotter loadings.

To close, these cap and ball pistols are just a hoot and provide me with a great pastime.

[mykeal]

Pyrodex and 777 have greater pressures and need about a 15% reduction in powder.
Nope.

777 is indeed more powerful and a 15% reduction is advised to obtain pressures equivalent to the same volume of real black powder.

Pyrodex produces almost identical pressures as the equivalent volume of real black powder. It is not significantly more powerful.

Thanks for the clarification on Pyrodex ! :D
