Ruger old army question

[OLDER THEN DIRT]

I have a ROA BP. I`m using Remington #10 caps & it doesn`t always fire them. I have to cycle around & hit them again. I belive this is due to the way Ruger desined the hammer not to hit the nipples. Does any one else have this problem, or should I be using differant caps? By the way, I use these caps on my other BP 44`s & they fire off everytime. Thanks in advance.

CCIs work fine on my Ruger, but I don't remember which size offhand. I don't recall if Remingtons have ever been tried on that particular revolver. (I generally just buy en-mass whatever's on close-out each year at Wallyworld.)

Having thought about your misfires a bit, it seems to me that since you get ignition on the second go around, your caps are not fully seated, almost certainly because they're too small. The first haammer impact drives the cap down far enough to achieve the required crushing of the compound against the nipple on the second try.

Try seating the caps more firmly (within reason)-or go to the next larger size. "Too big" caps can be retained on the nipples by making the skirt slightly egg shaped before seating. If you're using a cap dispenser, just deform them before filling.

BTW, I mark my dispensers (5 or 6?) that aren't dedicated to a particular firearm (and most that are) with the size and brand of caps inside. Makes it easier to work out what a new firearm likes before putting together it's own possibles bag.

This is almost surly your problem.

Cap sizes can be inconsistent even within the same brand batch to batch.

You can use a short dowel to seat your caps carefully.

There are two possible alternative answers to this problem, both of which I have experienced.

1) Old nipples: the head is slightly peened over, thus preventing the cap from seating right down.
2) New nipples: the head has been turned with a sharp edge, but the caps are ever-so-slightly rounded. This also prevents the caps from seating right down.

In both cases, the answer was to lightly round off the sharp or peened edge of the nipple with a fine file.

It's been some years but I had a an "Old Army" and as I recall I used #11 caps on it. I do know I never had ignition problems.

This question prompted me to look up the manual. Found a PDF version and for caps it calls for "...No.10 or No.11. (US) or equivalent." (page 11)

Here's a link to that manual if anybody is interested... http://pdf.textfiles.com/manuals/FIR...er_oldarmy.pdf

Number 10 caps are in theory supposed to be smaller in diameter than # 11 caps and is likely why they are not seating on the nipples properly.Notice the in theory disclaimer to cover my butt.
