A frequent area of confusion is the use of BHn to compare alloys. While BHn gives us an indication of one physical attribute of our bullets it doesn’t really tell the whole story.
Case in point. I can cast a bullet from straight Linotype and get a 22 BHn bullet. I can also cast a bullet from a far lower Sb, and lower yet Sn alloy then heat treat it. I can get the same 22 BHn this way.
Those bullets will behave in a far different manner in the gun and on target. The Linotype bullet will be brittle and prone to fracture. The “lower” alloy will flow rather than break. It will be far better for hunting.
How about a nice discussion on alloy and heat treating and how BHn doesn’t tell the whole story.
