The FBI violence stats for 2013 are out.

17. BJS & gallup

ezra: gun ownership has been steady since the mid-1990s, while murders decreased 50%.

You're compressing; household & personal gun ownership rates dropped from 1993 to 2000, even accd'g to your gallup link, & FA violent crime & murder rates also dropped.
The sharpest decline in HH gun ownership rates was from ~1993 to 2000 - gallup has it dropping from ~50% to 34% (99) & 42% (2000). Note how violent crime rates (& totals) dropped the most during that very time period of 8 years, then fluctuated slightly from 2000 - 2008 as HHGO rates leveled off. The two charts (gallup HHGO & FA violent crime rates) show a correlation (murder rates in next post).

From a firearm related violent crime rate high of 9.2% & 9.3% in 1993 & 94 - as HH gun ownership rates declined - the FA related violent crime rate also declined steadily to 1999, then fell to a low of 6.2% & 6.0% in 2003 & 2008. That's from a 25% to 33% decline. From 2008 to now evidently FA related violent crime rate rose back up, post Obama or Heller, I pick heller.

Highlighting the last two columns. Note the dramatic drop of nearly one million crimes in FA violent crime totals from 1993 to 2000 (1.55 million to 0.62 million), while as HHGO rates leveled off 2000 - 2011 there was a much less drop of 0.2 million. Note the dramatic drop in total murder from 1993 to 2000 (above chart), from 18,000 to 11,000:
