OK, I applied UBC to 3 rifles a couple of weeks ago. One of which was my M70 300WSM. I cleaned them thoroughly first - several patches with Hoppe's, then a brush with Hoppe's, then Barne's CR10 patches, then a patch around a brush with JB's, then more Hoppe's and CR10 until the patches looked the same coming out as going in!

Then a used the "solvent" that came with it as directed. Then applied the UBC with a bore mop soaked as directed in the instructions.

Well, today was the first time I could get to the range. Ran 15rds through it. Decided I would go ahead and clean it then to see what's up. It was honestly the worst fouling that I've ever seen out of this rifle - powder and copper!?!?!?! The UBC website says that the first cleaning will likely be the worst, and that it will get better over the next few times - I sure hope so!

Anyone else see alot of fouling initially applying UBC? Did it get better after the initial cleaning?

Thanks!

Yes, I experienced the same thing but I used 20 rds as my stopping point. Everything inproved after that. Didn't notice any difference in any group sizes. Cleaning them was the big improvement, 15-20 minutes is what it now takes to clean my varmint rifles (each). Before the coating, I was spending hours on each rifle, I'm a happy shooter.

Yeah, the first cleaning after the curing shots often encounters some fouling--just like the instructiosn say.

One thing you might try on the bext barrel you shoot-cure is only take 5 shots. That's all it takes to cure the stuff. After that you are just fouling the bore to no purpose.

How many rifle barrels will one "bottle" coat? Do you buy direct?

It depends on the bore size, but I would say 4-6 barrels. I do get it directly from UBC, www.ultracoatings.com.

Ok, I'll check them out. That link didn't go to UBC, it was some Go Daddy site - weird.
Thanks

This one will work. http://www.ultracoatingsinc.com/ Bear

BTW after curing my 35 Whelen the bore looked as if it was copper plated. Don't panic.

If you got the Outfitters link at the top of the page, you can buy it right here. Haven't tried it myself, but will one of these days soon.

John, are you saying go ahead and clean after 5 rounds, then shoot as normal? I guess I took it as it needs 5 rds to cure, but didn't understand that I should have cleaned it after the 5 rds and shouldn't have continued shooting.

I ordered mine through the Campfire when I ordered my next McM during the Christmas special.

I did 3 rifles that all use the same size bore mop (.277, .284, .308) and looks like I have enough left for 2 or 3 more.

UBC is fully cured after 5 initial rounds. There will always be some fouling during the curing shots because it takes a few shots to heat-press the UBC into the little imperfections in the bore. If you shoot more than 5 rounds it isn't cured any better, and the fouling picked up during the first 5 shots will attract more fouling.

Also, some bores will take more than one application for the stuff to reach maximum effectiveness, especially larger bores. I had to apply it twice to a .338, for instance. If you decide to apply it again, only clean rthe bore with solvents and nylon brushes, no abrasives or brass brushes. Otherwise you'll be "uninstalling" the UBC, to use computer talk. But in bores up to .30 one application usually does the trick.

Any thoughts re # shots for a revolver application? I am doing my S&W 25 this week. Would it require about 5 rounds for each cylinder chamber?

Ah, Thanks for that JB I was wondering about the 35 and a second application. In your opinion should I just apply a second coat after cleaning to be sure? Bear

No. Only one shot from each cylinder as you are not treating the cylinders, just the bore. Far as that goes, you could fire five rounds from the same cylinder and have the same results.

Yes, 1st use/curing was pretty fouled, but it cleaned up much easier than w/o it & it does get better from there.

OK, maybe that's why it seemed worse than normal - the patches were coming out with more black/blue than normal. It took several patches each with Hoppe's and Barnes CR10, but each patch was removing alot of stuff. Before it took alot longer until the patches came out clean.

Gotta get some more loads worked up and get back to the range next weekend to try it out.

I was intending to treat the cylinder chambers, too ....wonder if there will be enough heat generated in the chambers to cure it....hope so; those crud rings at the case mouth are not cool.

John,

If you want to treat the cylinders it should work there as well, but you probably will have to shoot several rounds from each chamber.

UBC makes any sort of clean-up easier. It makes cleaning a muzzleloader easier, for instance, and some muzzleloader manufacturers are apparently installing UBC in their factory barrels. It also makes screw-in shotgun chokes much less likely to pick up plastic shot-cup fouling, and if a little does stick it's much easier to get out.

cool. thanks. I think this will be a huge time/effort savings over the long run.

Hey guys I just got back from Shot and saw the thread. Your results are typical for the first firing. UBC works well in handguns. Coat the cylinders from just past the bullet case union to the end of the cylinder. Use a qtip for this and just do one or two very thin coats. Also coat the face of the cylinder. Don't worry about round count to cure just go shoot and wipe it off with powder solvent. I am going to my daughters house but will get back on line this evening. Thanks for the help John.

Five shots huh? Boy of Boy. I fired 5 to cure yesterday morning in my 6.5x47 Lapua then went on to fire 6-10 shot 300 yd ladders. Best get to cleaning!

How does UBC do in a frosty or lightly pitted bore? I have an 1873 Winchester and an 1895 Winchester that shoot good but have pitted bores. There is also red rust visible down in the pits even after quite a few rounds down the tube. Would the rust have to be completely removed? Quicker cleanup would be nice on these old rifles because I shoot them a lot.

Yes, remove the rust and anything else. It won't fill the pits, but it will clean better.

What corelokt said,remove all rust then install UBC. It will clean much easier. It will keep the rust from reforming.

Doug, When discussing medium bores like the 35 Whelen do you find that it is necessary to re-apply after curing and cleaning the first time to assure total coverage of the bore? I don't have a bore scope so kind of guessing here. Bear

Bear,
I haven't found it necessary however,you won't hurt anything if you do reapply. After curing you'll right back to .25 microns. I find reapplication helps only with M.L.due to low heat and pressure.

Even with 65 shots down the barrel to cure the UBC, cleaning was not that difficult. Just let Hoppes #9 do it's work. Wiped out the crud with 3 wet patches and then used a nylon brush to loosen up any touch carbon. Soaked in #9 for about 6 hours before wiping it out and hitting it 3 times with Barnes CR10 to remove all the copper. Looks good! Off to the range in about an hour.

Alan

Thanks Doug. Bear

Thanks Doug. Do you have any suggestions on how best to remove the rust? I suppose electrolysis would work but I don't have one of those units. I also have a rust remover named Evaporust that is supposed to remove rust without harming the steel.

Marc
Try your rust remover I've always used JB and elbow grease.
