Plan on buying bothI've looked into porcelain media, but never tried it. It's more expensive than stainless without any extra longevity. I would suggest you look into Southern Shine Tumbling media if you're having pins getting stuck. Southern Shine is stainless "chips" instead of pins, so they're much smaller. In 5+ years of using them, I've never had a chip get stuck in a flash hole.

I really don’t have that problem with the walnut media and I have tumbled about 10,000 cases with the same batch. I must be doing something wrong. Of course, it does help to have a lid on your tumbler bowl, but that’s just common sense.For many decades I used a standard dry tumbler with either corncob or walnut media. It got the brass nice and shiny, when it was new and clean. After that, you needed to add a bit of Flitz and a squirt of windex. When you dumped it, get a fucking hazmat suit and a respirator!! What a mess!
Some tumbling media has a larger partial size, therefore less surface area, therefore it gums up faster. I had a bunch of Lyman corn cob media that was very course, and it would gunk up and stop cleaning brass pretty quickly.I really don’t have that problem with the walnut media and I have tumbled about 10,000 cases with the same batch.

No shit you have a lid on the tumbler!I really don’t have that problem with the walnut media and I have tumbled about 10,000 cases with the same batch. I must be doing something wrong. Of course, it does help to have a lid on your tumbler bowl, but that’s just common sense.
No shit you have a lid on the tumbler!
I was referring to the toxic dust cloud that comes out when you dump it. Had you read the whole post, ( or comprehended it) you would know I said exactly that!
I'm also calling shenanigans on 10,000 cases on one batch of media. Unless you are using a cement mixer, a standard tumbler will hold 200-300 9mm cases and do a decent job. 300 is probably too full, I never counted them.
At that rate, that is 33 plus tumblings on one load of media. If you are talking rifle cases, make that 100 per load. The Dillon tumbler is bugger and would change the equation a bit.
I'm not angry at all. Your first post insulted me and pretty much called me stupid.
Hey! Call bullshit all you want. You’d be wrong, but I couldn’t care less. I’m just telling you what I do. You be you.
I always find it funny how angry people get over reloading practices, like there’s really only one sacred way to do it right.
Well, I’m sorry that you took such offense at my first post. I did not insult you nor call you stupid. If you read that into it, I’m sorry. I merely pointed out that my experience was much different than yours.I'm not angry at all. Your first post insulted me and pretty much called me stupid.
I was just pointing out the math in your statement doesn't add up for me.
I also noticed you didn't disagree with or dispute anything I said, you just said I was wrong.
I'm done, have a nice day.
Cold welding is a joke. 60ksi behind the bullet will release it from the case the same way every time. There is no amount of neck tension variation that can affect a rise from 0 to 60,000 psi behind the bullet in milliseconds.
I had some left over prairie dogs rounds from last year for my bolt action. I seated the bullets deeper so I could shoot them of an AR-15. The necks were definley bonded somehow. I did not chronograph the ammo, but it still shot bug holes out of my 223 bolt. The shorter OAL stuff, I broke the bullets loose in, actually shot a little worse.
And they never realize it because those bullets hit their target.I think more people probably have bullets that stick in the neck and they just never know it, because they shoot it with out pressing with it.
Never said it was either. I'm well aware of pressure curves and the effects of combustion chamber volume on smokeless powder behavior.The 60ksi isn't immediate, nor guaranteed.
Shot great at 100y only means so much.And they never realize it because those bullets hit their target.
When it comes to shooting, reloading is the absolute number 1 subject for old wives tales, superstitions, unproven theories, and plain ol bullshit.

I'm saying the friction of "cold welding" (which no one has ever been able to describe in actual scientific terms to my knowledge) is irrelevant in the face of 50 - 60 ksi

Cold welding - Wikipediahttps://en.wikipedia.org › wiki › Cold_welding
Cold welding or contact welding is a solid-state welding process in which joining takes place without fusion or heating at the interface of the two parts to be welded. Unlike in the fusion-welding processes, no liquid or molten phase is present in the joint.

We have possibilities with metal like galling, seizing, or corrosion sticking them together also.
Unless they are cleaning the necks with you know, SS media, to remove all carbon. The bullet would not need degreased.
No. Again. Maybe too small for your old eye balls.
What Is Galling? - Bortechttps://bortec.de › blog › what-is-galling\\
While cold welding is the merging of two parts, galling is the friction damage that follows cold welding. When two parts are cold welded and then moved by compressive forces, galling damage occurs on the surface of both materials.
Your assessment of cold weld VS galling is 100% wrong. A minute ago you said you cold welding had never been scientifically explained, now you are the expert. Oh yea, thats out 308buttpirate, the instant expert.
I'm sure it happens in other places, but the shooting sports, as you mentioned, seems to have a lot of old wives tales, BS pseudo-science, and "this is how it's always been done, so that's how I've always done it, and anyone different is wrong" mentalities.It's not, except in the minds of those who need to justify (to themselves and/or to others) why they do what they do.
Ok, Bill Clinton, thats not what you said.You love quoting things out of context. I said that I hadn't seen an explanation of cold welding, not that it didn't exist.
Can galling happen when separating cold welded parts? I'm sure it can, sometimes. I've also experienced galling between two parts that have never been cold welded, such as when pressing a shaft into a rotor for an interference fit. That's friction related galling.
I took your link and dug further, quickly educating myself on cold welding and pointing out conditions needed for cold welding that are highly unlikely to be present when one presses a bullet into a case neck. How about you address those points? Or do you not have the intellectual horsepower to do so?
I will take that as you saying you have no idea how to figure out the answer to your own question. Nothing that is press fit falls through.
