Brass jags

I agree. Just annoys me that 'any common copper solvent will instantly turn a patch blue'.
Clearly not.

I think it’s good information to know which solvents do or don’t.

Arguments aside.. Jags/Brushes are consumables. Just get the ones that dont dissolve.

@DShortt - Are you certain the jags you're testing aren't a brass looking aluminum alloy?

2 year bottle of Sweets 7.62 verses 12 year old Red Breast Irish.
I did'nt bother with the Irish since the Sweets worked as it always
has. Sure looks blue to me ?? Where'd I set my glass ??

Which one are you sippin on?

How much have you had to drink?

This thread is dumb.

So if it turns the patch blue then I figure in working on both jag and copper in the barrel, if it’s not turn blue it’s probably not working on either. Works for me

“Should have gone to Spec Savers…”
You will definitely be able to do a “Sniff Test” on the two bottles and if that does not work just a wee drap upon the tongue will instantly identify….

Glad I kept my mouth shut .........for once !

I don't have a specific analysis for them, but that's why I tried 2 different ones. I was paying no attention to anything but caliber when I bought them and months apart.

If you really want to party, go on mcmaster and order some honest to goodness brass and copper. Then repeat your test.

I noticed that the brush looks decidedly copper. I use these. Not sure if that matters.
As for jags, I just picked them up here and there when needed.

Why? The narrative is a bronze jag will instantly show a false positive with any common copper solvent. I questioned that.
I decided to check it myself after getting told to try and come back and apologize.
So, here we are.
Meanwhile, the bore scope tells me both solvents removed copper from the bore.
I never expected this to turn out this way myself. Had the patches turned blue immediately I'd have been fine with conceding.
I tested on patches because I don't use paper towels in my bores. Maybe that makes a difference? No idea.

Have you ever tried pushing a rope. If you had, you would learn that it is impossible. I am done.

Exact same brushes I use… and they turn blue before I can finish patching out my barrel. It takes brake cleaner to get it off of them.

I think it’s just time you concede that your solvents are so old they’ve gone dormant… or that you’re embarrassed and lying about the outcome of the test.

Either way…. I can’t think of anything else constructive to say.

Try your test with a bullet on a paper towel with difference solvents, that'd be interesting. You would have an answer then

Related question:

It common for shooters to use brake cleaner to stop the reaction on their brushes. Would ordinary 91% alcohol work?

I use alcohol. Works fine.

Not to add more fuel to this already smoldering trash fire, but:

Brass is an alloy of copper and zinc, however, it can also have tin or iron added depending on what the application is. That being said, there can be less than 40% copper in the alloy and it can still be "Brass"

Bronze, however, is mostly copper. Usually 80% or more.

The reason that is important, is that jags are usually Brass and depending on what other metals are alloyed in, it may not react to copper solvents much at all.
Bronze brushes, however, will most certainly react. So, if you are a "add solvent, scrub with a brush, then patch with a jag" you will very likely get false positives. If you don't use bronze brushes, you may or may not get the positives, depending on which jags you are using.
