No, none at all. It's not a tight fit but there's no room to spare reallyI'm thinking tapered bore. Is there allot of free space at the muzzle when you insert the jag?

@JohannesKepler, you really need to get a digital caliper to do some measurements. Calipers are cheap enough, generally less than $25. Digital calipers have a direct readout so you don't have the calculation issues associated with Vernier calipers. I need to have focus when I use my Vernier set, but I never need to replace batteries.
I seem to recall that you have a Loyalist Arms Brown Bess. I have found that most of them run loose on bore size. Mine actually has a slight choke. I would have expected the bore to get a bit bigger about 6" down the bore.
That said, I own two of them and they are very accurate, giving repeated measurements with less than a few ten-thousandths of an inch.
The problem with them is, they do tend to eat batteries and just about every time I wanted to measure something with them, the battery was dead.
For a few bucks more you should be able to find dial calipers. These have a mechanical dial on them and they too are very accurate. They also never need a new battery right when you want to use them to measure something.
They can also be used to make precision layouts of hole locations, etc.
You can get a spring inside caliper, but these don't have a lot of accuracy. You will get as much information from a 5/8" dowel rod. Tie a small bundle of cleaning patches with string as the patches may come off the rod. The rod should slide without restriction from the muzzle to the breech. Are there any sections that are more restricted than others? Mark those spots with a small piece of masking tape. Are these at a place along the barrel where there are underlugs? Any indication of a bent barrel?
I have a set of the Harbor Freight digital calipers and they give measurements within acceptable tolerance to my Mitutoyo Vernier calipers.
Oiled it right up, slid it down no problem until about 16 inches in where it wont go any further, tried a few times.Maybe try running it down the bore again but this time real easy so it don't get stuck. Oil it good first.
What is attached to the barrel at that point? Is there an underlug? Stock to barrel? Sling swivel? Something has to be there that has changed the shape of the bore at that point.
Great thought. I’d get the barrel off and see if you can see anything from the outside at the same spot. You’ve got a dent or something of the sort. Perhaps a weld was blown through or something strange like that. Put your rod down the bore to that depth without the jag on and see if you can feel anything.
Vise grips. Clamp on the rod and tap out with a mallet.Forgot to mention, it's metal, so it's a tad bit harder to get a good grip on it.
At 14" on my Loyalist Arms Long Land Pattern, I have the sling swivel underlug,View attachment 40657
Measuring the barrel at the suspected restriction os one of those instances where having a digital caliper would aid in the investigation.
Are you sure whale snot is really slick?I got a jag stuck at a shooting match in Maine. The guy next to me took out a C-Clamp, clamped the rod to an overhead rafter, and yanked the gun away from the rod/jag. Slick as whale snot. I now carry a c-clamp in my shooting kit (so I will never need it again.)
