I don't use WD40 for anything gun related to cleaning or preservation. I clean with room temp water and dry the barrel with alcohol patches. A little gun oil on a patch ran down the barrel one or two times and I'm done.
 
Just use day works for you. This has the markings of a 40 page argument on cleaning. I don't care if you don't like wd-40, or gas just fine, I don't care if balistol is "stinky" and causes you to need mydol. DO WHAT WORKS FOR YOU AND DON'T PUT DOWN WHAT OTHERS DO.

I won't even say how I clean my guns lest some crusty old Billy Bob go off on it. Works for me.
 
WD40 good or not has, or how you clean has nothing to do with op as to why this guys barrel smokes after shot.
Humidity related?
Some oil smoke after the shot?
Some grease in the breach as a protection during shipping?
Crazy stuff our guns do just to mess with us?

Don’t they all to some degree. Even my six guns, not only a whisp from the barrel but from the cylinders also.
 
I have a friend who has a .54 cal. percussion rifle. He uses only pyrodex RS in all his rifles. He also uses only musket caps for best ignition. After firing the rifle the barrel still has smoke pouring from the bore. This does not happen with his other rifles. I asked him about how he cleans his rifles and he does them all the same, that is hot soapy water, dry patches and a light coating of WD. This only happens with this rifle. He also cleans the drum with a pipe cleaner. Any thoughts as to what is happening? He has not fired black powder out of it yet but his other guns fire pyro just fine.
I tried pyro for all of one can. Seemed fine in my rifle, but in my pistol the balls got out of the barrel before all of the powder burnt, resulting in a second or so while it cooked off after the shot. Maybe your friend is experiencing something similar; the ball is gone, but unburned powder is cooking off slowly because it doesn't maintain the chamber pressure.
 
I have one 54 that smokes a little after shooting. I think it might be residue from the patent breach. Just a theory but I don't worry about it! 👍
 
bet the smoke is from residue of pyro burning when new o2 is introduced after the ball is down range.
I was testing batches of powder last night. found a bottle of pyro rs way in the back of the chest.
i was burning 5g of powder in a big ladle. the pyro left smoldering smut in the ladle after the poof! or should i say poooooooooooF! pretty slow compared to fffg.

That is what I was thinking that unburnt powder started to burn off after firing. I can't think of anything else come to think of it. His gun must have a place for it to accumulate down in the breech area. His other guns probably don't have that feature.

I think that is it. Maybe if he used more powder it would burn more completely.
 
This forum is getting "nuts" beyond belief. Seems all anyone wants to do is argue. A guy posts a question about why a barrel smokes profusely after being shot & it is immediately turn into a fight over the use of WD40. PLEASE stop this insanity! If you can't or won't contribute to an answer or theory about his question, just shut up!

nobody is arguing about WD 40 but you had to come here as a grumpy old man to start an argument. some guys were talking about WD 40 as being the cause of the smoke then a couple of JOKES were made. go yell at some kids who are on your lawn

Now that we are well into our second page of discussions and speculation about a rifle that we do not know the maker or how the breech is chambered, I'll add a bit of my speculation. A better answer could be given if we knew who made the friend's 0.54 caliber percussion rifle or what the design of the breech was. It would also benefit to know a bit more about the other rifles that do not smoke after firing.

My speculation is that he has a chambered breech. I also speculate that he cleans his rifle with a lot of liquid cleaner and stores his rifle after cleaning with a lot of oil left in the chambered breech that can't be dried out. Then the rifle is stored muzzle up so that whatever oil is left in the breech will leave large amounts of gelled oil residue. When fired, some of this gunk will continue to burn and smoke will be emitted from the muzzle for a short time after firing. I recommend for the friend to store his well cleaned rifle muzzle down so that the oil can drain from the breech and not build up that residue of smoldering gunk that burns after a shot is fired.
