Choosing a handgun to take to Maine on our annual deer hunt, I grabbed S&W 357, a box of handloads for rabbits if I scored a deer early, then on a whim I decided to grab a box of factory full house loads. Took a box or Winchesters off the top shelf and stuffed it in my ammo bag. Imagine my surprise unpacking to find I'd grabbed 351SL. No harm, but a reminder to be careful every time
