XRF scan will give you the answer. The rest will be educated guesses, some more educated than others.

Most people new to casting are well served by a known casting alloy. As you gain experience, you might find that for hunting type loads, a softer alloy will better serve your needs. That is just a...

Delkal, the COWW are wet or have been wet. Why invite the tinsel fairy? Not a good idea to add cold metal to molten metal. Please be safe.

I just rub on a little bees wax on both sides of the rubber ring. Sort of lubricates the ring, easy to tighten enough to not leak.

It is not at the bottom of the page but would be a few lines lower than the delete box and says something like "Delete this message".

If you decide to use pins, make sure they are below to surface of the wood or you might get a burn from the hot pin.

Perhaps a rough casting and then file to final form? Or proceed with your mold and use a slow centrifuge to force the molten metal into final form.

Looking at the illustration in post #37, I can see that the sprue puddle of each individual cavity is perhaps too small to remain fluid long enough to feed molten alloy into the cavity as the alloy...

This is probably the sticky that is being suggested.

I process a fair amount of range brass with a range of dirt and oxide formation. I use both corn cob and walnut media. I notice the dull look when the media needs to be changed due to build up of...

Hmm, most of the references I see say that lead melts at 621 F. Typo?

It was mentioned that the "linotype" the OP had was in letter form so it is not lino but perhaps monotype. When you are spinning your wheels testing unknown blends and alloys, you would do well to...

Are you using the powder measure mounted in a stand, or moving it from case to case by hand. Free handing will often result in some jostling and that will shift the powder around and can result in...

The most common way to deal with zinc contaminated alloy is to let it stand quietly while at casting temp and skim the dross about every 15 minutes until most of the dross is minimal. Then cast into...

Walnut hull will Scrub where the cob might be too soft.

When I use the dry media in the vibrating tumbler, I dampen several small cloth patches with mineral spirits and toss them in with the brass. The spirits seems to help attract the black debris. ...

Maybe this will help establish your value?

Lee has two different types of two cavity molds and have different alignment systems for the mold halves. Also the alignment areas require a little lube from time to time. Clean the molds if they...

Just skim and scoop off the dry material as you would with the dross left after fluxing. I use a cheap spoon with a small hole drilled in the bowl to allow the hot lead to drain out while retaining...

This is a heads up that at times some organ pipes contain metals such as zinc. You may want to do the acid test on the pipes before tossing them in the...

EMT is perfectly welcome to use whatever method he finds serves him best. Others might care to review this link to decide if it is worth following his method or not.

Please do NOT use a wood dowel to drive a slug through the rifle barrel. If it breaks or gets jammed you will visit a gun smith to have it removed. The bore diameter is the minor measurement of the...

Very interesting evaluation of the barrel. Too bad the really rough area is at the breech and not the muzzle. A shorter barrel would not be that big a problem. It will be interesting to see if ...

This is the link you are looking for to determine if you have an isotope container or not. And it is not one of these.
