I like many others on here, practice dry fire exercises. I was just wondering what everybody here uses for their backstop when they do so? I have heard of the 5 gallon bucket full of sand before. That seems like a good plan. I personally use a stack of old soft back books duct taped together really tightly. I know from experience, that bullets get trapped in soaking wet books, and they tend to sometimes bounce off of dry ones and land right in front of them. Any other ideas?
