I just saw a commercial against cigarettes… it was one of the “truth” series. Some dude goes into a firearms shop and asks about light bullets or low lead shot shells. The owner tells him there’s no such thing, and he draws a parallel to light and low tar cigarettes.
If they’re going to advertise as “truth” they should be a bit more careful. There are shot shells that contain no lead – they’re for waterfowl hunting where lead pellets on the lake bottom would get ingested and kill birds. There are also what equate to light rounds – ie. a 357 can shoot a .38 special round, although it has much less power behind it.
I approve of the commercials against cigarettes. I don’t approve of them spreading misinformation about firearms.
