Well since the ventilation systems don't go up range I couldn't care less. I'm not wanting the lead vapour coming from the gun from exposed lead bullets.
Lead poisoning is a serious issue. I recall a police range officer being hospitalized for acute poisoning after 6 months on the new range. (Not a range I worked on. They ignored my advise that that air velocity was too high.)
Assuming you hold the pistol in front of you, and that the ventilation comes from behind you, you should not be exposed to much lead from the primer or bullet.
The airflow by you should be not too fast (about 50 ft/min you don't want eddies of air current as around you) and should be laminar flow. This is best achieved by letting the air into the room from the wall behind you through multiple outlets.
A good test is to take a can of baby powder with you and sprinkle it in front of you. If you get any on you -you have air turbulence.
With good air, your lead exposure with any kind of primer and bullet should be about zero.
My 2 cents in seeing many ranges is that too many think increased air flow will solve the lead problems. Not so. It makes it worse.
Also, if you have to walk down range to change targets, you are kicking up clouds of lead dust with your feet, defeating the airflow system.
The Savage wet trap is expensive, but effective and clean.
