Poboyspecial found some .25in. welding steel and wanted to know if it could be used to stop various rounds. We know that most of your steel targets are indeed 3/8in. steel and obviously thicker. What would a thinner .25in. steel plate do?
We dug out a .357 magnum revolver with a 2in. barrel and decided to test the complete spectrum. We chose .38spl. then on to .38spl +p and then on to the heavyweight .357magnum to see if any of these rounds would penetrate the .25in. steel. Let’s see how they do.
Part II of this test we got rid of the tilt of the steel plate
This video was created by Mark Gottschalk and describes how he cuts aluminum for his Techno Fish. There is ample footage of the cutting process. Mark describes all of the parameters (feedrate, depth per pass, end mill chosen, RPM, etc.) that he uses to balance the best possible cutting result.
