lee hardness tester any good|lee lead hardness tester instructions : maker I have used the Lee with no trouble. Even used it to verify hardness of purchased cast bullets. It does take good light and a steady rest to place the bullet for reading the dimple. The Lee uses the same principle for hardness testing of metals. The two basic types of steam sterilizers (autoclaves) are the gravity displacement autoclave and the high-speed prevacuum sterilizer.

Standard Test Pack for Large Steam Sterilizers. Conforming to EN 285, EN 13060, CFPP 0.
I've conducted an evaluation of the Lee lead hardness tester work several control specimens to determine its usefulness in determining the BHN value for the purity of lead in the casting of round ball ammunition. In this PounderLabs video we discuss Brinell hardness testing for metallic lead and its alloys, give some important history about Brinell and Meyer and how the LEE Precision Hardness. I also use a Lee Hardness tester mounted in a microscope. It makes it's use fast, easy, repeatable and very precise. I also have “calibrated” my Lee scope using pure lead and using the formula for conversion. I have used the Lee with no trouble. Even used it to verify hardness of purchased cast bullets. It does take good light and a steady rest to place the bullet for reading the dimple. The Lee uses the same principle for hardness testing of metals.
I have a Lee hardness tester and in good light it is not bad to use. It seems to be pretty close giving repeating results on the same alloy or pure lead. I know it is not perfect but for the money I believe it to be a quality tool.
A 5-minute video covering the basics of cast bullet hardness and demonstrating Lee Precision's Lead Hardness Tester. I have one really good recommendation for a hardness tester that provides the most versatile testing of lead alloys. It can be used with cast bullets, ingots, slabs, etc. It gives a BHN hardness result, which can be directly referred to. The short answer is that bullet hardness plays an important role in accuracy as well as keeping your barrel clean. A bullet that’s too soft will leave heavy lead deposits inside your guns rifling grooves, reducing accuracy, and requiring substantial cleaning.
Quickly and precisely check hardness of your lead alloy. Exclusive conversion chart tells the maximum operating pressure of any lead alloy. Kit includes calibrated hardened steel ball indenter "v" block cradle snaps into standard press ram 20 power 4 lens optical measuring microscope.
I have been using the Lee Hardness Tester for a few years. It certainly gives consistent readings between different blocks of lead, but I could not put my hand on my heart and swear that the test matched Lee's Bhn chart exactly.This is the start of a series of videos regarding alloy hardness. I'd like to share my technique with you regarding how I use the Lee Hardness Tester. If you.
