Primer residue is your enemy. (The black residue on the sides of fired cases, plus the smoke and vapors from the shots you have fired.) Working on that basis, I managed to go from 0.96 to 0.55 in 6 months, and others have been able to achieve better reductions.
For now avoid all contact with lead:
shooting
reloading
sorting brass
soldering
non-drip candles
artist's paint.
The is an unproven hard rock miner's tale that dairy products can help.
Once you get your levels down to an acceptable level, you need to change how you do things with regards to shooting. When you shoot on an indoor range wear a P100 mask. Other people may get away without it, but you cannot. Also wear a hat and a shooting shirt that you take off before you leave the range (do not contaminate the passenger compartment of your vehicle). If contamination in your house is any sort of an issue then have separate footwear for the range to avoid cross contamination. Wash yourself before leaving the range. If you pick up brass wear disposable gloves.
When shooting on an outdoor range the only change I make is to not use the P100 mask.
Anytime you are reloading or handling brass wear disposable gloves.
If you tumble your brass add some used dryer sheets (Bounce or Downy) to the tumbler and throw these sheets away after each use. The sheets are black after each tumble which I suspect (but cannot prove) is primer residue. When your tumbling media starts to darken (primer residue) it is time to change the media.
Wash before eating when at a range or after reloading.
Thanks that's exactly what I had in mind... assuming my levels drop sufficiently in 3 months.
