Most of the lead vapor comes from shooting open base FMJ bullets and conventionally lubed lead bullets. Part of the base of the bullet gets vaporized by the heat and pressure of being fired. Switch to TMJ (Total Metal Jacket), hollow points or plated, and use powder coated lead bullets instead of conventionally lubed lead bullets.
In recent years the high muzzle blast cartridges like 25-06, 270, 30-06, 9mm, 454 Casull etc. just don't get shot much anymore. Instead I'm either shooting low velocity large caliber cartridges, or high velocity low powder capacity cartridges. In handguns I'm primarily shooting 44 Special (home defense), 45 ACP and 45 Colt. In rifles one of my favorites is lower level (Trapdoor Springfield safe) loads in 45-70...you'd be amazed how much damage a 300 grain hollow point at 1600 fps can do. And my other favorite a 6.5mm Wildcat that comes close to 6.5 Creedmoor performance with 10 grains less powder. 6.5 Grendel is similar to the wildcat but a couple hundred FPS slower. And like the wildcat I shoot, the Grendel is an extremely tame round, both for recoil and muzzle blast. Your ears will adore it...
Shotgun or 223 indoors is out of the question...too loud. I use a 45 ACP home defense carbine. With a much longer barrel than a handgun it pushes what is normally a 850 fps load in a handgun to a devastating 1000 fps (45 Colt level), and does it with much less noise than the handgun.
