Once you get the burner working properly, I might suggest wind screens around it so the heat all goes to the pot, an insulated jacket around the pot, and a lid on top. It’s amazing how much propane...

Power factor minimums in action pistol sports insure competitors’ hand loaded ammo aren’t all mouse flatus cheater loads. In certain divisions you actually score more points for the same hit if your...

…I have a large ultrasonic cleaner I use for cleaning out gunk in carburetors and after depriming the cases I put then in the ultrasonic for about a 1/2 hr and in the tumbler they go with just a...

Updates:

The polygonally rifled factory barrel out of another G17, fit in the aftermarket top end, shoots the same lot of ammo without leading or tumbling, and with good accuracy, so as far as...

I do know folks who think 128-129 PF is fine. If they had a 10 grain swing in a 124 grain bullet, based their load on a high weight bullet but were unlucky enough to have a couple light bullets...

Lead pot: are those balls ceramic? Do you get good cleaning of the extractor grooves and inside edges of the cases?

I’ve also used white vinegar to clean brass. The acetic acids works the same as...

I’ve never had that problem, but then my cleaning process for my (mostly once fired) brass has the cases pretty dry in a matter of a few hours at most, so no time to develop corrosion related issues....

Oh, I freely admit to indulging my OC side when it comes to alloy. From a practical standpoint, though, what I really want is consistency for the tens of thousands of boolits I cast each year for...

The frame is probably US Glock manufacture, though I don’t have it in front of me to inspect. The slide is aftermarket (basically I got one pre milled for a dot sight) with a mix of...

I got the same story from the PO about 5 years ago. It didn’t help that I was going to pay back most of it on outgoing Priority Mail shipments.

The more I think about it, the more I believe you and the others recommending a new barrel are right. I’ve always wanted to try a KKM barrel so, while it’s a month’s wait, I might be...

Well I repeated the bore slugging in all three barrels, (twice more in the problem barrel), all with basically the same numbers.

I don’t think it’s the alloy or coating, since I don’t get leading...

So I had nasty leading towards the muzzle along with keyholing and horrible accuracy in a new 9mm pistol barrel, using an alloy, bullet style, HiTek coating and load that had worked just fine in my...

Turns out I didn’t need quite so much diameter. Even without vise compression the 0.358” slug left a generous ring of swaged lead on the trailing end of the slug. Looked to me that I got the full...

Vice compression has gotten the shank diameter up to ~.365”, which I think should do the job.

I used a groove less bullet meant for coating, and figure the ogive will make it easier to start than...

Cast some pure 9mm bullets to use for bore slugging. Among several possibilities I need to investigate for leading in a new pistol barrel is a change in bullet to bore fit.

Got the idea here to...

Many tens of thousands of commercial and home cast HiTek coated bullets through my Gen 3 polygonal rifled Glock barrels without leading issues.

Now the new, more conventionally rifled Marksman’s...

The hassle factor of scrounging, transporting and then processing scrap lead is high. That creates a market for selling the product ready to go. Of course you’ll pay more, so it’s a back and forth...

Iirc it was member Ausglock who commented that he saw his lead levels rise when in contact with the (ime, very) dirty wash water while bare handed, with subsequent improvement when gloved....

I’m not a mold maker, but maybe a given cherry, designed with a certain amount diameter shrinkage in mind, can bore a cavity to slight different depths, giving different weights?

And just how...

I’ll be the fourth to vote for VihtaVouri N320, and will add that it meters very well.

Expensive, although just about all powders are at nosebleed prices these days.

I gotta think that somebody as experienced as Tom, who machines custom molds using sophisticated design software and cnc machine tools, knows what’s possible to make (“your design will cast between...

Maybe I read into it differently from what you got from the same statements, but I believe the cavity volume determines the weight of alloy the cast will have, and that Tom can alter that volume to...

I think member BNE, who has ready access to lab grade XRF equipment, ran an experiment with a very hot pot of alloy where he continually skimmed off the surface as crud formed, but never returned it...

Like you said, tradeoffs.

I got into wet tumbling to clean brass in an effort to avoid inhaling the potential lead exposure from the dust in the media, present despite mitigating measures. Then I...
