I posted this over at CGN but figured someone here could be interested. I am not trying to sell anything, just telling a good experience I recently had with this product.


So here is a story that I would like to tell a few folks about. Now, I am not sure if many of you have heard of Dyna-Bore Coat(formerly known as Ultra Bore Coat or UBC) before but I will assume most here have not as it has not been available in Canada as far as I know. Up until recently I was not even aware that this product existed and even if I had heard about it I would have doubted it as I am not a believer in "snake oil" cures.

Here is the product I am going to tell you about:

I wont go into telling you all of the details of DBC. Please read the above link for all you will need to know about it.

Here is the thread I started recently looking for this product with some more details:

Now onto my recent adventures with this product. So I recently bought a semi custom hunting rifle from a friend and well respected CGN member that was put together by Bill Leeper. I knew when I saw this rifle it was what I always wanted to build but never had the time to research and put together myself, but that is another story...

Upon receiving the rifle I slapped on a scope and was off to my range. It was quite apparent that with a clean bore this rifle was a tack driver but quite quickly all accuracy was lost(with witnesses and other folks shooting the rifle). Cleaning and different bullets were tried but nothing seemed to work. It would start off as a 1/2" tack driver and then spread to big groups with no consistency. Talk was in the air of lapping the barrel and all the way to ordering a new hand lapped barrel for it. I was informed by the previous owner that he had recently heard of a product that "could" just cure the exact issue I was having. I had some serious doubts but figured it was worth a try before sending it out for a new barrel, what could it hurt?

So after some frustration with the rifle and then the weather not cooperating I got my chance to scrub the bore clean and add the DBC and hope for the best. After doing all the necessary steps to the bore and adding the DBC and letting it cure overnight I was finally ready to do some test and cleaning runs.

Well, needless to say the difference was noticeable right away. Before treatment I could take as little as 5 shots and have a look down the bore and visually see that it was covered in copper (didn't matter what bullet). After anywhere from 5-10 good shots, accuracy was heading down the tubes and fast. Now with the treatment added I had 34 rounds down the bore all with excellent accuracy with almost zero visual copper in the bore. The last 15 shots, one target at 100 yards were just over 1", basically one 1 1/4" hole in the target.

Now, I have not run more than the 34 rounds down the tube to see how far it will go but so far this product is very impressive. It took a bore that would copper foul badly with as little as 5 rounds and lose all accuracy and turn it into a bore that will run at least 34 rounds with no loss in accuracy and almost no visual copper in the bore. It is now very easy to clean as well. I would spend two or three evenings trying to get all the copper out of the bore in the beginning, 20-25 patches with long soaking periods in between. Last night I cleaned it after 25 rounds down the bore and it took me 4 patches before they came out clean.

I still have some more testing to do but so far I am very impressed. Everything that John Barsness has written about this product has proven to be true so far. I would like to thank Jordan Smith from CGN for selling me some DBC when it was proving almost impossible to get into Canada.

Is it a cure for bad fouling barrels? I cant be 100% sure yet, but with the results I have seen so far I can think of a few more bores in the safe that will be seeing this treatment. If it makes them easier to clean with no loss in accuracy I am all for it!

My last venture into a product similar to this (won it at a shoot) I ruined some brass loaded to pretty mild specs. it seems introducing potions to the bore will totally throw your resultant pressures right through the roof.

Being that it was Nosler Custom 280AI brass, worth more than I care to admit (before I found a cheaper source), I was mighty steamed.

Before you use a product like this make sure you are backed off to no more than starting loads before you touch a few off.

As for copper fouling, Wipeout has been my god send.
