I have 3 ROA's. One SS, One Blued, both with target sights. Awhile back I ran into a SS high polished fixed sight version to make up my 3rd one. I took both SS versions out today at the range. I had never shot the fixed sight version yet. I've always used #10 Remington caps and they have always worked reliably.
Shot the target sight version first for awhile, everything great as usual.
Next I loaded the Fixed sight version, lined up the sights, pulled the trigger, misfire, backed up the cylinder and tried again, fired that time. Next time was also a misfire. Tried the other shots, some shot and some didn't. If I backed up and tried again they would eventually fire. Next round I made sure to get the caps down as far as I could. This seem to help some but still had misfires.
Not sure what the problem is, perhaps the clearance between the nipple and the hammer must be too great. I measured the nipples with a caliper and compared them to my target sight ROA, seemed to be the same overall length. The diameter might be a tad larger, the #10's seem to fit a little snug in comparison. Could this be the issue, perhaps it needs #11's?
Doesn't look like the unit was dry fired a lot, hammer seemed to be in good shape. One thing I do notice is that my target sight ROA has SS nipples and the Fixed Sight polished version has steel nipples (both had the Ruger hex head style nipples so they don't appear to be after market).
Anyone have a similar issue?
