Dan, you can't just jump into the middle of a thread and pass judgement on something you know nothing about...you have to read a whole thread to understand context...of course it's easier to shoot things out of a bore...EVERYBODY KNOWS THAT.
The grease hydraulic type method is just one alternative that was being discussed if the obvious ones can't or won't work for some reason.
Since I have personal hands on experience doing it recently I can assure you without question that steaming hot water with a squirt of dishwashing detergent gets the bore & breech squeaky clean in no time just like it always does when I clean a barrel that way after a range session...that's what hot water and dishwasing detergent is designed for...to cut through/clean grease off of dishes, pots, and pans.
ANYONE who cannot shoot a ball out at the time it was loaded has a problem...
The gun is improperly made and its impossible to get powder behind the ball, in the case of percussion guns has no nipple wrench or in the case of a flintlock he is using FFG for prime and lacks the intelligence to grind it finer.
Stuck balls are ALWAYS fouling or lube related or have been upset by hammering (this will really stick them). If a fouling based problem simply dump some water in the bore and let it set for 10 minutes it will invariably come unstuck.
But you cannot shoot it out since the water will pass around the ball in most cases. If the shooter has a puller it is then possible to pull the ball by first pushing it down perhaps an 1/8" if its not hard on the breech already. SOMETIMES they are really stuck to the point they will not pull easily. Thus I recommend shooting them out if at all possible.
If contaminating the powder is an issue, ball stuck part way while loading, use less water and dump it out after 5-10 seconds leaving the gun muzzle down. The ball should be movable in a few minutes. The shooter should then rethink his loading process or patch lube, or learn to wipe the bore when loading starts to get difficult.
My take, based on about 40 years of gunsmithing as a hobby and professionally is that pumping a barrel full of grease is a Rube Goldberg solution to a simple problem.
Its goofy stuff like this, and the response I often get my opinion of wacky ideas, that make me not even respond to a lot of what I see on various shooting sites.
I would further point out that using hot water for cleaning invariably browns the inside of the barrel and is poor policy. When I lap a barrel I wash out the oil based compound with solvent.
I would also point out that some 1/4" zerks are 1/4x27 PIPE THREAD. The 1/4x28 types are invariably a TAPER thread as well and I DO NOT recommend screwing a taper thread into a non-tapered hole. If you enlarge the threads you may experience "blown nipple syndrome". An event that sometimes results in people converting to flintlock ignition.
If you want to continue to give advice of this caliber go for it.
I will refrain from commenting on this further.
