Double February

I just checked the stats for March – we did almost 105,000 hits in just that month alone, which was double what we did in February.  Helped along by this surge, of course, which I found was in large part due to a posting (which I still haven’t found) on the AR-15 forum.  Which brings us to within 15,000 hits of 600,000!  Depending on how the response to the article in Concealed Carry Magazine goes, I won’t be surprised if we break a million hits before this summer.  As Jim K said:

Wow!! I still find it hard to believe just how right you were about the amount of interest in our beer bet 🙂


So, cheers to all who have helped to spread the word!

  1. Great site-read about it today and I appreciate all the time, effort and money that have gone into producing this data.

    Have you considered publishing the ‘energy’ in foot pounds for each round/barrel length combo in your results? That would be helpful in comparing disparate results both within the same caliber and against other calibers.

    As I’m sure that you are aware, the formula for calculating energy in foot pounds is static and is:

    (Bullet weight in grains) * (velocity in feet per second) * (velocity in feet per second) / 450400

    Thanks again

  2. Thanks, Robert – We have debated whether to do the calculations and post them, and have gone back and forth on that. We’d decided to not do so to this point, in order to keep the data displayed easier to read and understand – thinking that for the more serious ballistics geeks the calculation would be simple enough to do, but that for the larger pool of people it might be confusing.

    It’s a judgment call, no doubt. Next weekend we’ll be doing the next round of tests, and I think I’ll kick it around with Jim K and Steve again.

  3. […] Well, April is already as good as March was, and sometime in about three or four days we’ll break 700,000 hits to the site. The Concealed […]
