NOE 356 HTC 135 load data

Anyone casting this bullet have data for it. I can't stop it from keyholeing at 7 yards and out of my glock 34

I'm going to guess that your are using the factory barrel, with polygonal rifling, and that the bullet is stripping in it rather than being properly spun by it. There are a lot of warnings about not using lead in the polygonal barrels because of this issue. The danger is that as each bullet strips it leaves lead in the corners of the polygon which not only makes the next bullet strip even more easily, but it can accumulate until you get enough blockage to cause excess pressure.

There are people who've said they fired hundreds of lead rounds successfully in a polygonal barrel, but then over the space of one magazine full, suddenly had lead start to build up and raise pressure until they got a burst case and damaged to the gun and themselves. I don't have one of these and haven't experimented with it myself, but if I am right about the cause of your problem, then you are treading on thin ice.

The general solution is to get a Lone Wolf or other aftermarket barrel with conventional rifling for shooting lead.

Before you buy a barrel so you don't have to worry about cast bullets, you should do a cost comparison between lead+new barrel and coated in stock barrel.

I think it will take a long time to amortize a new barrel unless you are casting your own bullets from free scrap lead.

Why would the coated bullets not be able to strip, too? The coating is even softer than lead. Since he's invested in the expensive NOE mold, he could try coating them, I suppose, but it's not clear to me the result is guaranteed to be different.

They are powder coated and have shot other lead bullets coated the same with no issues and good accuracy also with no leading.

What kind of coating are you using? What are you sizing the bullseye to? Is there any leading?

Leading could be the culprit but if no leading is present that rules it out.

I shot that bullet some but haven't found any real accurate loads with my limited testing. I shot mine in a lone wolf barrel anyways so my results wouldn't necessarily apply. I believe the powders I used were Bullseye and HP38. There is overlap between 124 and 147 data. That is where I started.

Powder coat and 356 no leading at all

reddog81 · November 17, 2016, 12:31 PM

I'd try sizing to .357 and see what that does.

What kind of dies are you using? If your using the Lee factory crimp die I'd back off on that a little.

Using Dillon dies and crimp just enough to do a no go go test in my tightest chamber

I think, given their great recent popularity, we all know what powder coat bullets are. I'm trying to ascertain whether or not there is a reason the coating won't strip and let your bullets tumble anyway, assuming stripping is the cause? The coating is a resin, and not harder or stronger than lead casting alloy.

If your bullets are undersized, the coating may help them fill the bore better, which could help, but it's not guaranteed, that I can see.
