Marklart,
I have been using the 410 in earnest for wild Calif quail about a season or so. I could not be more pleased. There's something about using a 410 that brings me pleasure I never thought a difference in guage could make. Also, my success on quail with the .410 as compared to 20ga is not that different. Since I'm not going hunting for subsistance, I figure what ever gives me more pleasure is a plus.

If you've moved down in gauges before, you know the issue of success becomes mostly a mind game. If you keep a positive attitude, you have a much higher probability of success. The 410 challenges you more than the other gauges that way.
