For that matter, the MSM's Der Stürmer approach towards the NRA and gunowners suppresses membership in the former and therefore the education the latter might otherwise get from reading the member magazines.
Perhaps I'm oversensitive, but being part of this fight since the early 1970s (sic) bias from the MSM is assumed and the tropes are trivial to detect. Counterwise, not genuinely biased reporters and editors are so marinated in gun grabbing bias---as you are unless you read a lot from other sources to counter it, even if you're an active gunowner, even a NRA member (or so surveys tell us about the latter)---they'll automatically use them even if they weren't really meaning to be biased. Perhaps a style vs. substance problem, since the problem is real ... but, again, the dismissive attitude towards the NRA and the blackout on the NSSF shows the limits of their research, and at some point "they're the generically clueless MSM" excuse doesn't cut it.
Did the article give any examples of customers being harmed? In these situations, it's almost always an occupational danger, since owners, employees and volunteers get massively longer exposures, and are also responsible for cleaning the place, which can also expose them to lead fragments at the end of the range. I think nowadays almost all centerfire bullets are jacketed, but ubiquitous and inexpensive (until very recently) .22 LR rimfire aren't jacketed, or not seriously. Probably less of a threa
I also wonder why OSHA and the state OSHAs aren't on the ball. The usual suspects on my side, the NRA and NSSF, are very serious about this (the exit of the very nice NRA's HQ range in Virginia has two hand washing stations you can't miss and as mentioned publicity of the dangers, and see https://www.google.com/search?q=nssf+range+lead), they publicize the dangers, the NSSF helps ranges ... the OSHAs could be more heavy handed if they wanted to be, as long as it was clear to these orgs they weren't just trying to shut down ranges. And there's funding to be had for ranges (add "fund" or "funding" to the prior search).
