I was an OSHA safety officer for a chemical company .. so I understand the OSHA standards and OSHA methods of enforcement and am familiar with the violations that the company got cited for..
2 main issues: noise and lead
Other : MSDS issue
Noise can be abated by better hearing protection (muffs + plugs can get the noise down to being OK) .. everyone knows a gunshot is ~120 decibels .. I've never seen OSHA make recommendations like they have here (lower caliber projectiles) ... so this is an easily solved issue ... acoustic tiles are not a bad idea
Lead on the other hand is another matter. The lead exposure (due to dry sweeping mainly) is clearly a concern ...
The employer clearly needs help to get this lead issue under control (and its out of control in this instance ~ hardly OSHA improperly clamping down) --
I think the employer knows the hazard should be addressed (he gives respirators to his workers) but he does not have the knowledge of how to address the problem correctly.
Bring contaminated clothing into the office space and where you eat? Come on ... and yes, lead exposure is very serious -- it can mess you up!
They only have in indoor gun range ... no outside range that I can see .. http://www.illinoisgunworks.com/gunrange/gunrange.htm .. a little 25 yd range, 10 lane range...
And OSHA fines cannot overburden a business .. they are not meant to be punitive ... so, they'll do what they can and the fines will drop to about 15-20K ...
