BoydAllen said:Recently I did some general cleaning with Pro-Shot Copper Solvent IV, and was impressed with how it worked on powder fouling. Some of the shots were with Reloader 10X. I have also tried CarbOut with a bronze brush and believe that it does a pretty good job. As far as hard carbon in the throat goes, I think that the trick is to not let it build up until brushes and solvents won't touch it, and Iosso is required.
I would tend to agree with this statement.LawrenceHanson said:Over the years I have used a number of bore solvents. I will buy a new solvent and use it for a while thinking it is the best solvent I have ever used. Months will go by and the new miracle solvent seems to lose its effectiveness. So I buy the next latest miracle solvent and find it works better than anything I’ve tried before. A few months later it no longer does the job as well as it did initially and I try something new again. This cycle has gone on and on for years with me. How can this be? I believe that many solvents degrade quickly over time and lose their effectiveness. Solvents tend to volatilize quickly, no matter whether they are in a little sealed bottle or not, especially under warm temperature conditions. If you go through a lot of solvent in a short period of time, then you are getting the most use out of that chemical. But if you use that chemical sparingly over a longer period of time I believe the product becomes less effective due to extended evaporation/degradation. Some appear to “keep†a little longer than others. I have reached the conclusion that many solvents are most effective only when they are relatively fresh or preserved. In general, the older they get the less effective they become.
You might have picked the C4 bottle with the least amount of dust on it.
In any case, I hope it works out for you in the long run.
