It used to crack me up back in the Army when guys would freak out when I’d pull the cleaning rod and brush back through the bore.Are there a lot of those ? I've never really researched it. I just saw a piece of this in a youtube short and then the algorithm put the full video in front of me later on. By far the most extreme method I've ever seen.
Barrel break in also makes me laugh. I see these guys at the range shooting 1 round and cleaning the shit out of the barrel for 15 minutes and then repeating for all day.There is probably not a more contentious subject than "barrel cleaning".
"barrel break in" is definitely up there.
But the good news is that we can now argue about " large sample testing"
Thank you! It's so frustrating talking knives with people about how this steel is so much harder than that one... but even CARDBOARD will dull even high quality steel over time. Just maintenance your darn tools!...Yet I still manage to dull my steel knife blade cutting straw when I'm slicing open hay bales for the cows.
what about tunersThere is probably not a more contentious subject than "barrel cleaning".

I started keeping a box cutter on the tractor for that very reason...Yet I still manage to dull my steel knife blade cutting straw when I'm slicing open hay bales for the cows.
I'd rather argue about large sample groups though...it's the new rage.
Does it shoot straight now? Find that out before making it a .338I'm going to rebarrel my 308 in the near future. It may have some life left in it but I want a faster twist. The bore does look a little rough in places and it's rusted once before from being neglected for 4-5 years just standing in the safe so it has some pitting in it.
I'll post some pics later. Then I'll try out the Dewalt powered cleaning rod and see what happens.![]()

Anybody seen this before, or tried it ? Lol.
It's a more, aggressive approach.
It is funny. When lapping, the compound is embedded into the softer material to abrade the harder material....Yet I still manage to dull my steel knife blade cutting straw when I'm slicing open hay bales for the cows.
I'd rather argue about large sample groups though...it's the new rage.
I think that video was in response to some pics @Frank Green had posted that showed massive gouges cutting through the lands that was done by aggressive cleaning with some kind of lapping compound .I just want to see somebody repeat this process on a relatively new (<500 rounds) benchrest or f-class rig...with before and after groups at a moderate distance.
Doing this to a 4K+ worn out tube that isn't anything but a tomato stake anymore isn't going to change my mind. Slap that brand new pipe on there and hog it out with your Dewalt with some before and after groups and you will make me a convert.
Plus you'll revolutionize barrel cleaning, and everyone will remember your name.
Paper, including cardboard paper, contains kaolinite or calcium carbonate. You're not just cutting cellulose fibers. Carboard is also not a "fine" product and contains a lot of other random impurities and abrasive particles.Thank you! It's so frustrating talking knives with people about how this steel is so much harder than that one... but even CARDBOARD will dull even high quality steel over time.

Bullets having more effect or not, damage the crown and see what happens to your groups.
Using a brush with an abrasive, I believe is that he said would wreck a barrel. I don't remember any exchange between the two over the subject.I think that video was in response to some pics @Frank Green had posted that showed massive gouges cutting through the lands that was done by aggressive cleaning with some kind of lapping compound .
I’ve got three barrels in the shop. One is a 308win. Has only 500 rounds on it. Cleaned it with an abrasive and a brush. Shooter took or should I say changed the bore and groove size by a full .001”. Accuracy is junk.I just want to see somebody repeat this process on a relatively new (<500 rounds) benchrest or f-class rig...with before and after groups at a moderate distance.

It was KG2 bore paste and being used with a bronze brush.I think that video was in response to some pics @Frank Green had posted that showed massive gouges cutting through the lands that was done by aggressive cleaning with some kind of lapping compound .
Any one have links or a have done long term cleaning vs not testing?
Eric Cortina did and interview with a Hornady guy and one of the points he made was the biggest difference they saw was in velocity and pressure increase. Not much of an effect on group size.

Another barrel with 110 rounds fired on it. It’s a 260AI. This guy didn’t wreck one but wrecked three barrels in a row!
The pic I post a lot is a 284win with 800 rounds on it. The barrel started having accuracy issues at 100 rounds! Right now the bore measures .279” and the grooves are at .2855”. When we made that barrel it was at .277” x .284”. So the shooter basically polished out a full .002” out of the bore (tops of the lands) and at least a full .001“ out of the grooves.
I’ve also got data on another 308 barrel. Barrel shot 1/2” groups at 200 yards. If I recall the barrel only has 250 rounds on it. He cleaned it once with Flitz and a brush. Then it went to shooting 2” groups at a 200 yards.
Yes the process on how the guy cleaned the 284 win F class barrel was repeated to the T on a brand new barrel. Same damaged showed just as fast.

Yes.The abrasive is the real issue though correct?
Non abrasive materials with a brush made of a material softer than the barrel material shouldn’t have any negative effect?
So, you think a brass brush will hog out a stainless steel barrel??
Also, your ask has already been done. Lou Murdica cleans his barrel with a drill. He uses a nylon brush only because metal brushes with flake off and then he has to clean the piece of the brush out.
If you’re not familiar with Lou, give it a look. This is years old news. Plenty of top BR and F class use drills with brushes.
They just don’t worry about showing the world on forums because people just kick and scream saying it doesn’t work.
Same with the PRS crowd insisting people don’t shoot at 25+ power. Many of the top shooters shoot stages at max or high power and just don’t want to argue on forums.
My problem isn't a metallurgical one. I'm not smart enough to carry on those conversations.
My position is that if you are going to make an over the top video with drastic extremes to prove a point...use your new new barrel instead of something that you pulled out from underneath your workbench (that's where I keep my old barrels at least). Then give us some sort of data points to back up your position. A borescope (I own one too) isn't going to provide any way of measuring if you took half a thousandth off your lands while you just broke free and spun a bunch of abrasive material against them (your point with Lou using nylon because metal brushes break off and leave material is noted here).
I have no doubt that the guy is a stand up dude. However if you want to change people's minds, perform it on something that has value still, not something that is worthless. I'd be a lot less skeptical if he had chucked up one of his nice rigs and done it on a serviceable barrel. I'm sure it is inadvertent, but it came off like the elixir salesman who says it isn't harmful - while making the dude strapped to the chair drink it. That is my point.
You get some hard data points that show I'm not going to significantly degrade my barrel's life, and I'll be right there next to you with a drill in hand. I am not stuck to anything, I promise.
I'm only a few years into the "money into noise" hobby, but as someone who's dealt a lot with metallurgy, it seems like there are a lot of folks cleaning far too often. From the forces and actions involved in internal ballistics, it seems to me that the worst enemy would be build up in the chamber and not the actual lands/grooves of the barrel itself!
For one it depends on the chemicals or type of cleaner being used.Can you give us an example of how using non abrasive chemicals every single day in a barrel would harm the barrel?
What exactly hurts the barrel if the chemicals are non abrasive and the brushes are far less hard than the barrel?
Where does the damage come from and why, explained scientifically, from your experience in metallurgy?
So, you think a brass brush will hog out a stainless steel barrel??
Non abrasive materials with a brush made of a material softer than the barrel material shouldn’t have any negative effect?
As someone who is far, far away from the engineering arts, the whole “soft wearing away the hard” has always confused me, but yet it happens all around nature.Where does the damage come from and why, explained scientifically, from your experience in metallurgy?
skip the first 119 minutes and re read my post lolFrank Green would be a great guest on Erik Cortina's podcast. We could nerd out on barrel cleaning for 2 hours!
Nobody is denying a softer material can wear harder one.As someone who is far, far away from the engineering arts, the whole “soft wearing away the hard” has always confused me, but yet it happens all around nature.
What does “wear” even mean?
Engineers are not always the best explainers. Sort of like most physics and especially math teachers.
It’s not clear cut, and I do not have the knowledge or expertise to explain it well. I’ll try my best.
It’s not just how hard/soft something is, it’s also how fast the materials are moving, what other particles are in-between the hard/soft, friction, melting, pH, temperature, impacts, pressure, particle charge, etc.
For example, how can a river cut through granite? (I know this is not an exact analogue about hardness, as water isn’t a solid, and particles in the water help the cutting. But see the end of my post)
How are you scratching your sapphire watch crystal? Are you sure it’s a scratch, technically?
Why do brake rotors ever wear out? (Not talking about warping)
Why do carbide-tipped circular saw blades ever dull? (Not talking about hitting nails)
How can fishing line groove the metal guides on a fishing pole? (ceramic guides have less issues)
Diamonds…how are diamonds polished?
Back to: What does “wear” even mean? I am pretty sure it’s not just about hardness & scratching.
My guess is that thinking about the above examples and indeed, the entire brush-bore-abrasives-chemicals (i.e. CLR) issue, in terms of just hardness/scratching is the first mistake. It’s not just that, there are many other factors.
Look here for starters.
Please reread some of @Feniks Technologies posts on this thread and tell me otherwise? He’s a standup dude, but he’s wrong here. On this forum, in general, you’ll often read that a soft thing cannot scratch a hard thing.Nobody is denying a softer material can wear harder one.
Uh, you’ve somewhat reiterated one of the unspoken axioms of my whole post above?The point is when done properly it will not cause a noticeable negative effect. Improperly... ehh you could fuck shit up with one stroke.
It appears one of the top barrel manufactures says leaving the debris in your barrel will cause corrosion and pitting. Which I am assuming is more detrimental than the immeasurable wear from a proper clean after use?
Might happen next week!Frank Green would be a great guest on Erik Cortina's podcast. We could nerd out on barrel cleaning for 2 hours!
the point is the amount of effort it would take for a bronze brush alone is in the realm of improper. No one is saying it can't with the caveat that you aren't doing it like a retard. at which point the problem is not the tool but the operator. judging your response the latter seems it might fall in your realm.Please reread some of @Feniks Technologies posts on this thread and tell me otherwise?

What is missing is that “scratch” means one thing on the Mohs scale and quite another in layman’s terms. “Wear” is more like it to people like me way back in the peanut gallery.

Also, take a gander at the link below for example damage. It’s not as hard to wreck your barrel as you think. Especially if you have OCD.

How and when to utilize abrasive bore cleaners
After reading @Frank Green talk about cleaning and carbon ring removal I decided it’s time I take care of my neglected barrels. Some of my barrels are getting up there in round count, and cleaning carbon is getting harder and harder. Jb bore paste is what Iv seen some recommend as a mild...www.snipershide.com
You wound me, o’ capitalization-master, catching me “miss representing” everyone. Sigh…View attachment 8058551
you are miss representing what people are saying

This is exactly what happened to my 308. I was sick when I dug it out and cleaned it before I was about ti start shooting it again. Pushed a patch through it and it came out orange!Same thing when you hear.... I don't clean it for a long time! I'll guarantee you that if you put it away dirty for x amount of time and the environment you are in....the barrel and the fouling will react with the air itself and the barrel will corrode it will pit.
I really didn't intend for this to happen. Just wanted to see if anybody had done it and what their experiences were. I'm going to do it then post the results.Classic barrel cleaning thread where everyone's opinion is right and other people are stupid.
