What about Barnes banded solid copper?
What about Barnes banded solid copper?
it is rather small.. less than 1/8in diameter and under 3/4 inch long.. been a while since i took one apart so im not really sure..
Barnes had to discontinue almost all of their banded solid line. There's only a few left that you can purchase all in larger calibers.
I have been looking all over the world for tungsten carbide rods that would be suitable for a core. I found a company in China will make them for me they would be 4.75 mm in diameter and 8 mm in length I should be able to make a core out of those. The problem is, they are still $.80 each so 500 of those shipped cost me $433 and I Do not have that kind of money. Unfortunately it's a minimum order of 500. So, I don't know what I'm going to do, apparently there's no place in the United States that works with tungsten carbide.
Then theres the whole "shall not be infringed" part of the law.
I don't know why you think no one in the US has it. A quick look in Google and I see about 10 companies that handle it in various sizes.
Just a quick look at my go to for everything McMaster Carr

Thanks 1911. What's the best way to cut them to consistent lengths?
GONRA goes nuts on this stuff.
Pretty sure when ya'll refer to "tungsten" you really mean "tungsten CARBIDE"?
>>> Yeah - its important - not just some GONRA niggling! <<<
There are all sorts of technical gun nut articles out there that "just slopply ignore the difference".
"Homogeneous tungsten metal alloys" AND
"cemented tungsten carbides" (binder is usually Cobalt metal)
are BOTH used for military AP cores!
They are WAAAAAAAY different!
Depending on which size you need, with the smaller size rod it is easier to just break them. Drill a hole the same size plus a few thou. and drop the rod in and snap it. Not terribly consistent, but it is quick. The larger ones you'll need to use a diamond tool or diamond blade. I would use the thinnest blade you can depending on what type of saw you have. High speed, lots of cutting oil and a slow advance. If you have a lathe just use a collet holder and diamond tip cutoff tool.
Yes this is all in ref. to tungsten carbide. Straight tungsten is rather soft, harder than steel, but not a pain to cut. Tungsten carrbide is very hard. Cemented tungsten carbide is used all over th place, most lathe tools are cemented carbide. It is much easier to make any shape and be very consistent with it.

It's not that I was after anything cheap, it's that I'm totally new to tungsten carbide is a material as a whole. I prefer to find United States companies and it further, Michigan companies, and if possible local people. I did look, but I had a bit of trouble trying to find anything in the United States. I appreciate that link however.
