That's a bummer! I'd start by not hunting on State lands, since it sounds like that's the only place affected. You are going to find steel & non-toxic shells a lot more expensive, whether you purchase or reload. For waterfowl, the standard was to at least 1, generally two shot sizes larger than you used in lead, i.e. if you were using #6 lead, go to at least #5, preferably #4 in steel. I suppose the same would apply to doves, probably #6, but if you could find #7, it might work well. I've seen it available for reloading, but it isn't common by any means. If you go with Bismuth or Heavishot, your price per dove hunt is really going to sky rocket! Be sure and thank your government for the big favor!
