ruger old army misfires

No oil in gun at all. Dry and clean. I know it is a cap problem. Since they all fire second time around. If i load the cylinder 3 times in a row. Same problem. I cannot push the caps on further. But the hammer does and then fires 2nd time around. If i was in a gun dual i would have to tell the other guy to wait until i excercized my cylinder. Beam me up scotty.
 
Thanks boys. I will keep fooling with it. The fact that there is no complaints on the italian guns. At least not like the roa's. Tells me this is a common roa problem. When it shoots it is very very accurate. Talk to guys again sometime.
 
This IS NOT a common ROA problem. I know over a hundred guys that competetion shoot ROA's and I've never even heard of this problem until now.

It is a cap problem only in the sense that they are the wrong size for the nipples.
 
Spooker,
The one cap you did not mention is the Remington#11. It is shorter that the #10 and will "bottom out" sooner and maybe let the cap primer compound get up against the top of the nipple when seating. Try the Rem#11s. They fit larger nipples and have more "give" than other caps like the CCI/WW & RWS with harder walls. They fit larger nipples than the CCI#11s.

It may be that the top of the stock nipples are larger in diameter than normal and that is preventing the cap primer from reaching the top of the nipple with any cap.
 
Interesting

I remembered this thread fron a while back and had to comment as I had a problem I've never run into before. (Had to do a search to find this post again).

I had Remington #10 caps in my capper and they were perfect for my ROA. I knew I was getting low so recently I bought 2 more tins only this time they were CCI. Dumped a tin in my capper and went back to shooting. Had a heck of a time getting them seated properly. I thought, what the heck? :confused:
Had several misfires. I thought the nipples were fouled enough he caps just didn't want to seat. When I cleaned the pistol, I had one of the clean nipples out and checked it with a cap for fit. After trying several caps from this tin, none fit correctly and were all too tight. I set them aside and tried several caps from the second tin I bought FROM THE SAME BATCH. They fit perfectly. I got my mic out and double checked nipple and both tins of caps. The 2 tins averaged over .010 difference! Sorry, but that is a LOT!

In disgust I threw the undersized caps away. Quality control issue I'd have to say.

BUYER BEWARE. I've never had to do this before but from now on, when I need caps, I'll take one nipple with me and check several caps from a tin to be sure they're correct. :confused:

Not at all surprising.

I've said many times on this and other forums:

You don't get three decimal place precision for 4 cents per cap. Cap dimensions WILL VARY SIGNIFICANTLY from batch to batch.

And you do understand, don't you, that there is NO STANDARDIZATION with respect to cap size numbers, and nipple dimensions? No. 10 CCI's and No. 10 Remingtons are not even close to the same dimensions.

That's good to know.... I am not crazy after all! I bought another tin of CCI #11s last week. See if they fit any better....
