Thanks for the replies. I'm with you in spirit. Too much of any thing is lethal; the same applies to lead or water. That's why I used the qualifier of exposure.

I don't look down on off-season for improving skills. What was getting my goat is hand-wringing about steel's effects on the games. Everything is changing.

The biggest change I've seen in the shooting sports is how many now consider a modicum of effort beyond their comfort zone in hunting birds or game.

That's a bigger problem for our sport than steel's influence on anything.
