I have never been able to replicate a chain fire from the nipple end despite trying with 5 different revolvers. over the course of many thousands of rounds. I have had chain fire from the front with under sized balls.
I think the chain fire thing can and does happen from either end of the cylinder. All it takes is the right circumstances. Just because one person hasn't had it happen to them doesn't mean someone else has not experienced it. I have a Walker that was real nasty about chain fires, I found the nipples were under size on the threaded end after getting hit in the face by flying nipples. After tapping and treading the nipple holes to accept TC Hotshot nipples the chain fire problem has not plagued me since.
Another way is if the chambers are not truly cylindrical. If they have a taper to them, then as the bullet is seated it is swaged to a smaller diameter. On firing, recoil can cause the ball to back out of the chamber slightly, ending up in a slightly larger portion of the taper. Now the bullet is undersized to the chamber.
It maybe that chain fires can come from the back end, also. I would think this would easily testable by firing with no caps on adjacent cylinders.
Have this saved might help. I have found that RWS 1075 &1075+ fit all my guns that have nipples/cones for #10 and #11 caps.anyone who finds current production nipples that are properly sized please post and let the rest of us know.
Right there in my post,,,,,PDF Pages 15-16.Can you give us a synopsis or tell us a page number rather than having to wade through 43 pages to find the relevant bit?

when in a pinch that is all you can doI have pinched roughly 3 thousand caps in the last 3 years without a chain fire..
It wasn't just few grains of powder. I managed to dump a measure full of powder all over the end of the cylinder. I brushed off the bulk of it and figured the rest wouldn't cause problems. The lube on the cylinder held enough powder to set off two chambers.Were the conicals not oversized enough to get a tight fit, or?
I'm not seeing how a few stray grains of powder would be much more of hazard than the gush of fire exiting the chamber?
I feel setting up your revolver for the nipples you plan on using is almost never considered and should be !Recent purchase of TOTW nipples specifically stated for #11 caps and #11 CCI caps would fall right off if turned upside down.
I shortened the nipples on a knife grinder until the nipples would stay on and then cleaned them up some just to make them look better. Nipples are tapered cones.
This was on a SXS shotgun, as D Yager suggested shortening may become a problem on a pistol if the hammer fall doesn't hit them properly.
Later I found that Knights "Red Hot" nipples from OX-Yoke were the proper size, anyone who finds current production nipples that are properly sized please post and let the rest of us know.
Thanks!
Dang, I hope you pay more attention to detail when working on other peoples guns than that loading mess. So much for the safety of heavy shamfer of chamber mouths.It will get your attention when or if it happens. Last one I had was about a year ago on my 1860 Navy. I got sloppy and got powder all over the front of the cylinder and stuck in the lube over the conicals I had loaded. It fired off two chambers besides the one lined up with the barrel, it got my attention.
So I have a chain fire from getting messy on my own gun and you imply that my work is sloppy? This is coming from a guy who pretends to understand the Colt platform?Dang, I hope you pay more attention to detail when working on other peoples guns than that loading mess.

it doesnt take long hanging out on gun forums to see that guns owners are the most perfect people in world history. NEVER make a mistakeSo I have a chain fire from getting messy on my own gun and you imply that my work is sloppy? This is coming from a guy who pretends to understand the Colt platform?
