A couple week before MZ season I shot my Savage w/Pacnor 45 and it loaded fine. About two weeks later when I loaded it a day before season to check I had to hammer down the bullet. There seemed to be a rough spot about 15 inches down. I clean with 50/50 alcohol and #9 between shots. For short term storage (3 days to 2 weeks) after I clean, I use Bore Scrubber to clean and it has a light rust protective in it. Load is 100 gr BH209 Full Size Bear Creek 245. This is an annealed all copper bullet and it shoots and performs great. I switched to HB sabots and 240 fury for the season and it shot great also. In fact I might stick with that load so I don’t have to mess with sizing. Now after the season I used a Lyman borescope to take a picture of the bad spot. To me it looks like molten metal. Any Idea of what caused it and how I should try to smooth it out?

Can't help out on this but quite interested in hearing what people suggest and what you ultimately found it to be.

Is your load 100 gr by weight or volume?

100 by weight, it is a smokeless barrell.
Tried a few things and have more info- Tried copper remover and Butch’s Bore shine. No evidence of blue on the patches. Also tried bore paste 20 -30 strokes, Neither seemed to help much.
I thought about full sizing a Barnes 275 and using some bore paste or fine compound.

Another Thought- I started using LOCTITE LB 8060 Silver grade Anti-Seize stick a couple years ago. You think some compound could have fused in the barrel?

Have you knurled any bullets with files? A tooth could have broke off and gouged the barrel.

Kinds of looks like lead to me.

I have looked at this quite a bit. Does not seem like a gouge or copper. I would tend to agree with those that have felt it was lead. If so should not be too difficult to remove, they certainly have processes with lead in revolvers for removal.

Update- Tried About every kind of bore cleaner, I have some Bore Tech coming 200 strokes Copper scrub pad. 200 stoke UPS bore paste on a patch. I took another bore cam picture. Doesn’t look like much changed. Any Ideas? Or just more scrubbing?

How big is this blob? And we just has January 1st not April 1st right? looking for a baseline

I guess about the width of the land, 1/8 inch

Very strange!
Here is my $.02
If it were anything from the barrel itself, then there would need to be a corresponding "divot" where this material was removed from.
Since that would most likely be fairly obvious, I'll assume that you did not observe anything like that. I tend to think you had a blown sabot and the bullet yawed wildly in the bore, and this is bullet material.
Unfortunately .45 is not a common size for bar stock, so somehow you need to scrape this off with a rod softer than the steel barrel.
If it were me, I would probably take a piece of 7/16 or even 3/8 aluminum rod. Find paper or cloth to take up the gap on ONE side of the rod so to make the rod a snug fit to the bore. ( NOTE: THE ROD WILL PROBABLY ROTATE WITH THE RIFLING, SO IT MAY TAKE TRIAL AND ERROR TO SEE WHERE THE PAPER/CLOTH NEEDS TO BE IN RELATION TO THE BLOB ) Push the rod down the bore until it hits the obstruction. Then LIGHTLY tap the rod enough to at least deform what is there. Remove the rod, and inspect with borescope. If you see a deformation to the obstruction, then it is something softer than the aluminum. I would continue until it is mainly removed then go at the balance with a bronze brush.
Be very cautious, as you could damage the barrel if you wedge the rod and keep smashing it with a hammer.

I just had a thought. Full size a copper bullet , Barnes 275 maybe, sharpen the end, drill a hole in it and use a machine screw to fasten it to a 3/8 brass cleaning rod and use the rod and bullet to try to dislodge some material.

If you run the pointy end first, would it possible lodge the bullet in the barrel?? I think the flat end or slightly concave might have a better chance of not having a wedging effect. I might be wrong, just a thought

I am pretty sure he meant sharpen the base radius end, make the base to shank a sharp edge, like a scraper.

Just a thought. Have someone make a hard brass alloy jag within a few thousandth's diameterof the bore. With a sharp leading edge. Install it on a heavy brass range rod...gently TAP it a little and remove it. Look for damage on the leading edge of the jag. Then borescope again and see if there is any change Just a thought Drop

Drop, I think I could take a 50 call jag, I have a bunch, and turn it down and try that.

I would try plugging the muzzle end of the bbl. and filling the bore with a good bore solvent then stand it on the end and let it set for a few days or a week, then clean with a wire brush. I would be afraid of getting something like a jag or a full formed bullet stuck in the bbl. and the more you pound on it the harder it becomes lodged.

If it gets stuck I can pound it from the other end.

If it gets stuck I can pound it from the other end. Just dont get it stuck to hard or it will mushroom and be hard to get out Drop

I ruined a Brux 25 caliber barrel mushrooming a jag from the front side. In some scrap yard there is a barrel, a jag, and part of a cleaning rod waiting to be melted down

If its lead you can us boiling hot water and pore down bore then bronze bore brush right after and just keep doing this and the barrel will get very very hot so don't hold it. you can us a funnel to get it in the barrel.

Would it hurt to try a tornado brush, just thinking out loud.

Here is the update. Just got back from 2 weeks in Florida and was ready to tackle this issue. First Picture is original. Next picture is after 200 strokes with copper wool. Last picture is after using a brass jag that I turned in a drill to just fit the barrel. I also used some bore paste on the jag and tried the copper wool again. I sharpened the front edge of the brass jag and when it hit the blob, I tapped it lightly with a hammer. You can see int the picture where the rifling cut into the Jag so it is a tight fit. I kept doing this about 15 times. I think it removes a little each time but it is slow going. Any Ideas appreciated. I will probably just keep doing the same. This barrel shot 240 Fury real good with a sabot even with the bump so I always can shoot that load. I can feel the barrel is a little tighter at the muzzle and I think that is desired and I don’t want to screw that up.

Round # 3- I tapped he jag by the bump both ways. Then I would turn it 1/6 turn and repeat six times until all the lands were covered by this process. Then I sharpened both ends of the jag. I repeated this process 3 times. I then sharpened the back of a Barnes 275 XPB and tapped it down the barrel. I turned the bullet and repeated 3 times. If you look at the picture of the Barnes you can see where the bump scored the bullet every time I turned it. By the picture it doesn’t look like it did much to the bump in the barrel. It seems like the copper or brass is too soft to do much. I think I might just try to shoot it with sabots and if it still shoots good, just live with the bump. I will post the target when I get time to shoot.

Just a thought. Measure down to exactly where the debris is stuck to the barrel. Do the same thing you are doing. But first get it good and warm with a heat gun? Not a torch for sure but I bet a good heat gun will do the trick Drop

What bullets were you using when this happened?
