Hornaday Ammo Recall: 500 S&W 300 grain FTX Custom Ammo Loaded Too Hot to HandlePosted on February 22, 2012 by Nick Leghorn
Item 9249 Recall
Apparently the fine folks at Hornaday have made a slight calculation error during the loading of some of their 500 S&W handgun ammunition, called by some the most powerful handgun ammunition on the market today. The effect of that slight miscalculation is that you can now blow up your handgun (“excessive chamber pressures” in damage reducing spin-speak). Make the jump for the press release.
