Which is, at it's core, a de-facto ban on all shooting; I've written my congresscritters, and I suggest you do the same. Emails are great, yay emails, but nothing gets a reaction like signed, hard-copy letters flooding a desk. Sebastian from Snowflakes in Hell has info and multiple links, to include the NSSF webpage detailing how the EPA is trying to push the ban. The NSSF also has a sample letter to congresscritters that you can use, although I prefer to put my thoughts into my own words.
By the way, if you've never written a letter to your Congress Critters before, a good start is right here: www.congress.org. Put your ZIP code into the box on the upper-hand right, and it'll tell you exactly who your congresscritters are. Click on their names, and it'll take you to their info pages. There's a tab labeled "Contact" that has their State addresses and D.C. addresses. Copy and paste those into whatever word processing program you use, and you're off to the races.
Did I just date myself with that whole "Word Processing" thing? I think I did. Ah well, deal with it.
