Unfortunately my Gibbs is dead, the barrel didn't last long.
I suspect the steel of these barrels is poor.
A short load of a video that I made with the borescope, it is also evident that the tool to finish the lands has climbed and crested a step.

As in Pedersoli Gibbs? That's not a very good looking barrel for a very expensive rifle. What has caused all the rust?
Long Live the Gibbs!
Boil the barrel 30 minutes. Then scrub it out with a bronze brush. Then go shoot it.

Exactly. The proof is in the pudding.Originally Posted by missionary5155
Send it to me. I'll name it Lazarus.
The early Pedersoli Gibbs 45 cal rifle was made with some of the best barrel steel ever created by Mauser. It is an expensive material to make and Pedersoli used it on their top tier rifles,nothing wrong with Pedersoli barrel steel. As others have pointed out it looks to need a good cleaning.
It does look like those are deposits on the steel, not pits. How many rounds have been fired and what load?
I'd be tempted to show it to Pedersoli and see what they say.

not so this time!!
long live the GIBBS, not this time

Looks like you have been shooting pyrodex in it.
Maybe or didn't give it a good enough cleaning and oiling. I'll bet there are pits under those clumps of rust.

Bore scopes ruin many barrels.
Agree. Clean it and shoot it and ignore the bore scope.
Some years ago, several companies got bad steel for their barrels. It was German steel, and it didn't match the US specs. I suspect foreign manufacturers were getting the same steel, and didn't do any testing on it. I condemned two separate batches of barrels that had used that steel, making me extremely unpopular with the companies involved.
The solid soft lead bullet is undoubtably the best and most satisfactory expanding bullet that has ever been designed. It invariably mushrooms perfectly, and never breaks up. With the metal base that is essential for velocities of 2000 f.s. and upwards to protect the naked base, these metal-based soft lead bullets are splendid.

Is the following link yours from 2015 ?

I've had a few Pedersoli rifles show up with dirty and lightly rusted barrels from sitting at distributors for a few years, all but one cleaned up well. In your blog at Pedersoli you note citronella candles, margarine and other things used for lube is it possible some of, or something in what was used may have added to the corrosiveness of powder residue .

You didn't use BP of some type and then not clean it thoroughly , did you? Ballistol is not made far from you.
Margarine as lube? Never heard that one before but I'm pretty traditional I guess. People can get worked up over some stuff shown by a borescope that won't affect the shooting. As missionary5155 said, boil it, scrub it and shoot it before getting too down on it and from now on clean and lube that thing.

I was sure to create a storm in the forum.
Unfortunately I'm not the only one to have these problems, years ago the manufacturer changed the type of steel for the manufacture of its barrels and it is no longer as good as it once was.
Even the broaching process for the lands is not the best, rotomammeling would be much better.
However I always cleaned the Gibbs as soon as I got home, with boiling water and soap, dried and lubricated.
Other friends say it's erosion from the heavy charges I use (100 grains 1 / 2FG), with patched bullets, the metal undergoes a thermal shock and reboils are created.
Once I was shooting the GG with 60/65 gn of FFG and it was very good, then there was a decline in performance, so I started with the PP.
Hear hear, so far I have burned 12 kg of black powder which corresponds to 26.5 your pounds, maybe that's why it came to an end.
