A Bullet Casting Journey

I spent the better part of several months conducting a series of experiments aimed at improving the quality of my home-cast lead bullets and identifying which parameters of bullet casting actually have the greatest impact on bullet performance. I wrote up the results of my experimentation in the following document: A Bullet Casting Journey .pdf […]

Does Cast Bullet Hardness Change over 1 Month?

Does Cast Bullet Hardness Change over 1 Month? It’s been a month now since we cast up a batch of water-quenched, and air-cooled bullets as part of our ongoing lead hardness testing project.  Have they changed since they were first cast, and if so, how?  Lets go ahead and test five bullets from each group […]

Does Cast Bullet Hardness Change after Powder Coating?

Does Cast Bullet Hardness Change after Powder Coating? The practice of powder coating ammunition is quickly gaining momentum among the cast bullet community, and it’s not hard to see why.  Although tedious at times, powder coating bullets can reduce or even eliminate the need for conventional bullet lubes as well as further reduce barrel leading. […]

Does Cast Bullet Hardness change over 24 Hours?

Does Cast Bullet Hardness change over 24 Hours? In my last article, we took a look at some tests comparing air-cooled and water-quenched bullets, and reviewed the data from both.  During the preparation for that post, I took it upon myself to cast enough ‘spare’ bullets of both varieties to perform additional testing in the […]

Lee Precision’s Lead Hardness Test Kit

Lee Precision’s Lead Hardness Test Kit In this article we’ll be taking a look at Lee Precision’s Lead Hardness Test Kit.  The first thing people usually ask about these is why you’d ever want to test the hardness of cast bullets to begin with. The short answer is that bullet hardness plays an important role […]
