I’ve previously mentioned the JBM Ballistic calculators in the blog. But now there is a new Backup Ballistic Calculator –a circular slide rule–created by Todd Hodnett of Accuracy 1st.

Reader Travis B. recommended the blog Laptop and Rifle. Travis gave quick summary of the blog’s content: A guy that used to work for Google (a smart guy) buys vacant land and blogs his experiences living there full time. It includes setting up a Hut, toilet, outdoor shower, and solar power. He fails miserably in many areas but it is interesting, regardless. It might make a good case study or would generate interesting responses from your readers.”
