As far as my round count not adding up, I'm on record here stating that I don't top off. I'm also on record at THR and at S&W forum saying the same thing and I've been saying it for years.
We're frequently told that anything we put on the Internet is discoverable so in the (unlikely to the point that it would literally constitute God's plan for my life) event I'm ever arrested over a round count I'm pretty sure I can prove my case without too much trouble.
