This is what I would worry about. Lead poisoning is not pleasant for adults. I know a guy that got pretty sick. The guy that went with him every time did not suffer at all...but he stopped using that range. Lead exposure in poorly ventilated ranges is going to be very dangerous for a pregnant woman and the baby.The other thing to think about is the exposure to lead. They should not use a indoor range. And it is not only the bullet that contains lead but the primer also.
If you have to ask, then it's not worth it.
When I researched it, I came to the same general conclusion. We also skipped concerts and other loud noises.An audiologist on a different forum said:
"Pregnant women should avoid steady-state noise levels over 115 dB (that’s really loud and not commonly found outside of heavy industry and the military) and impulses over 155 dB. Consequently, pregnant women should avoid shooting weapons that are more powerful than a .22 caliber rifle or pistol. It makes good sense for pregnant women to avoid loud equipment as well, particularly if their bodies come in contact with the devices. "

Back in January, 1972 my wife went duck hunting at 8 months pregnant.
I'd think that shooting FMJ would yield less lead exposure than .22lr.
Fully jacketed bullets may limited exposure to lead, but if you have an exposed base, that lead vaporizes when firing...and primers expel their own junk that you can breathe in too.I'd think that shooting FMJ would yield less lead exposure than .22lr.
Why take the risk?
Who probbaly knows NOTHING about any of the issues raised here.
