TUBB DUST

Nobody in shooting ever made anything or did anything for free that I know of... if you find someone who is chambering barrels for free one, let me know, I have a few projects.
 
Screenshot_20191217-132350_Chrome.jpg David doesn't need money... I can assure you of that. He really does the things he does, because it is what he does.

And that says 500 ROUNDS between cleaning....
 
Who knows what's in the stuff but there is nothing new.

This powder makes me think of Caterpillar "Break In Powder" which came from Caterpillar in a can with a Caterpillar part# on it. Getting the piston rings to seat on a new machine or a fresh overhaul in the old days was problematic at best. This was back when men were men and hot headed profane language was used to communicate problems. With the old oils if you didn't build cylinder temps right away the fresh cross hatch in the liners would glaze over with hard glass like deposit that was just like diamonds. I don't know how many engines we pulled apart to hone and re ring to stop horrendous oil consumption and slobber. It was a lot and some were glazed up again in a few weeks. I'm sure Cat quickly tired of the expense to go in and pay the dealers to re ring not to mention the flared tempers, some were so bad we had to put new liners in. The dealers received a service letter announcing a new break in powder to cure the problem, "Caterpillar Break In Powder" which was induced via the air intake into the cylinders. The engineers eventually spilled the beans to the dealers it was Bon Ami. Probably a special formulation from the scouring powder chemical engineers to resolve a specific problem but non the less it was Bon Ami. It worked and worked well.

Sorry to venture off shooting but just had to share a little history.
 
Well you guys keep shooting 500 rds. without cleaning the barrel makers will all love you....at least its good for the economy. I'll refer back to what Barnum said....

Pt Barnum never won 20 something national championships and world records in ELR

DOING EXACTLY WHAT THAT POST SAYS.
 
I find it hard to believe that a 6XC will last 4000 rounds with accuracy, depending on how you shoot it.....very hard to believe. Even with dust.
 
[QUOTE="urbanrifleman, David doesn't need money... I can assure you of that. He really does the things he does, because it is what he does.
He does it FOR money, that is the reason as you say he doesn't need money....
 
Never really had bad copper build up or problems on my custom barrels. I'd like to not have to put it back in to shoot well. Maybe it's the powders.
That glassy wet look gives me the heeby jeebies!
 
And totally not true. I spoke to David specifically about his ELR Barrel that he won the Nationals with this year and he said he hasn't cleaned it in like 700 rounds. I admit I don't remember the exact number but it was something around 500-plus and he bore scoped it and put it on Facebook for everyone to see that there was no copper in his Barrel or muzzle brake.
 
Now for some history on this subject, seems shooters are bad about well I just started and all this is the newest and latest. When"moly" hit the scene early 1990's it was the greatest since sliced bread we would never need to brush again. But we were losing alittle velocity everyone said it was because the moly made bullets slippery. Jim Borden says nope its a flash inhibitor. People say no way so Jim figures out how much moly to add to powder as the same as coating bullets. If memory is correct it was 28 grs per 8#. guess what he was right uncoated bullets and added to powder drops velocity which reduces fouling...Graphite,moly,danzac and guess what HBN all do the same thing. I have tried everyone coating and uncoated bullets...now I will add to the Tubbs fire lapping system that is the rage guess what it was first introduced by ... The late Merrill Martin in the early 1980's who started NECO......nothing much new is there....

That is very interesting about the moly. I bet that would help the powder not clump so much in a drop. I'm not sure Tubb dust doesn't do something very similar (possibly reduce static). It has been discussed that guys are reporting less overthrows with H4350, but it's pure speculation.

I don't think Tubb ever said he invented abrasive bullets... he just makes them and sells them. From my testing they work exactly as they are supposed too.

Tubb Dust takes almost exactly 28 grains per 8 lbs. Isn't that interesting? Decoppering agents are very real. And they do work. It's not snake oil.
