Great video by our friends a Forgotten Weapons. I became convinced of the real cause of chain fire some time ago, but still appreciate shaving a thin ring of lead up front.
I too believe in what I call, Time In Barrel. There is a recoil, lifting of the Barrell that must be taken into account. In Heavier rifles this is lessened by the weight. A light firearm will rise more IMOThere is a factor called "barrel time". A heavy recoiling rifle will shoot higher with lower velocity loads because the muzzle will rise slightly with the bullet still in the bore. A pistol that has some appreciable recoil shoots to different points depending on the shooter's grip. If it didn't recoil until the bullet had left the barrel it wouldn't matter if you used a loose or tight grip. So I have to respectfully disagree with M. De Land. Just disagree, not arguing. After all, maybe he is right and I am wrong. Besides, he can probably out shoot me. I agree that the video doesn't show any noticeable recoil before the bullet leaves, but it takes only a very tiny movement to make a big difference in the impact point. That's one reason I'm not a very good shot. I forgot to say that this is a great video.
Yes , understood intent before viewing video, that is why I alluded to Sam Colts comments about chain fires originating at rear and not front of cylinder.As the original poster, I intended to show how much more fire is circulating around the rear of the cylinder than the front. Nothing about recoil or how many guns can you tie to a tree (WTH?)
If it's slo-mo video of 1860 Army revolvers you want, then that's what you get:
Advance to the 6:40 mark if you want to see the guns firing. Every ignition spark is flying straight up, not out. As if the cutouts around the nipple have some role in deflecting the flash away from the other chambers.
In the first place I am not indignant, secondly I quoted not about barrel rise or blow back no mention was made of either, thirdly the OP in a later post alluded to chain fire as I was pointing out.When you quote someone talking about barrel rise under recoil and then someone replies about barrel rise under recoil+blowback, you do not have the ground to get all indignant about how there'e no mention of chain fire going on.
Very interesting photo ! Perhaps a bit longer barrel or a bit less charge would be beneficial. Reminds me of a 60 grain load I fired in my ,50 cal pistol, much fire and un burned powder down range.View attachment 71076
I'm new to the forum and read this thread with interest. Also never posted before.
Picture is of my son shooting a Colt Walker. I always marveled at how it captured the blast at all three areas: the muzzle, the front of the cylinder, and the nipple. Notice how far the hammer is pushed back. Also it caught the reflection of the blast in the glasses.
Yes, I use a lighter charge now when shooting that gun.Very interesting photo ! Perhaps a bit longer barrel or a bit less charge would be beneficial. Reminds me of a 60 grain load I fired in my ,50 cal pistol, much fire and un burned powder down range.

until it does! that will wake one up! i have in 50 or so years never had a chain fire either, i send a request upward every time i fire my revolvers, that he sees to it i don't. then i do my part.This article tells how to avoid chain fire and how he found no evidence of originating from the nipples.
http://www.geojohn.org/BlackPowder/bps2.htmlI decided to try his experiment myself. I have pinched loose caps for over 50 years with no chain fire, so I tried leaving the caps off of adjacent chambers. Guess what? No chain fire. Emboldened I decided to load all six chambers and only cap and fire one. Still no chain fire. No matter how many times I tried it would never chain fire.
That is a good example of what I was talking about bullet travel up bore counteracting recoil until clear of muzzle. When one thinks about it there is a series of action and counter action beginning with hammer drop, cylinder movement forward inertia then discharge, cylinder moving reward , powder mass converted to gas, bullet hitting the forcing cone and moving forward with barrel friction until ball exit.That's a great photo. Also interesting that the muzzle doesn't appear to have started to rise yet. I'm sure that it did.
I believe barrel gap plays a part in this as well because the cylinder is driven forward at hammer fall increasing the clearance at the rear for fire to travel at discharge. Also I think caps splitting open play a part in fire deflection increasing chain fire risk at the cone.This article tells how to avoid chain fire and how he found no evidence of originating from the nipples.

Just remembered Paul Harrell mentioned in one of his videos that he tried the same thing with the same result.I decided to load all six chambers and only cap and fire one. Still no chain fire. No matter how many times I tried it would never chain fire.
