1Lb 158-190F Low-Melting Point Bismuth-Based Alloy Ingot, Cerrosafe Metal Ideal for Metal Casting, Barrel Casting, Measuring, Chamber Casting, Lead-Tin-Bismuth Alloy Easy to Melt

It is probably the easiest way to check your chamber or test out you molds before you commit to reloading or casting.

This is a low melting metal which is only limited by your imagination. I got what this product page said I would get, 1lb. I plan to use this in molds to make metal figures. So far melting has been easy and I have no complaints with this product.

This bar was right on the weight and is potentially one of the cooolest things ever. I'm kind of inexperienced as a metalurgist and although I fix a lot of things I had never come across bismuth outside of a chemistry class so of course I thought this was amazing on first sight. Then once I realized I could do anything with this I was infatuated with this and now other metals. This is a wonderful product to give to someone inquisitive or handy. It creates a root starting point in the imagination that you can grow many things out of. This is an item of contemplation for me and in fact if I keep it around it can become distracting.

Works perfectly for chamber casting.

This is a good budget alternative to cerrosafe and, metal being metal, is very possibly the exact same stuff without the name brand premium. It melts at the stated temperature, as confirmed with some hot water from the microwave, and flows and pours well. Good stuff and a fair value, so I can highly recommend it.

It looks like a piece of aluminum, but it is much heavier. My scale said it was right on 1 pound. I cut off a small piece and dropped it into a pan of boiling water and sure enough, it melted. I plan to use this to check the chamber sizes of several old rifles that I own. The metal can be used and then re-melted to use it over and over.

I'd rather buy expensive one but undermeasured When I received.... Bad experience

I have a casting machine form the 60's and this is what I need to give it a good spin
