I hunted a state class A area with a friend and it was brutal. We got there a little late (don't ask) but knew where we wanted to go. Were walking out at shoot time and it was a spectacular barrage once they started to arrive. I didn't see one person not shoot because the birds were low and they might be shooting at someone. As we were walking out a guy shot one swinging on it from about 40 yds away from us with his swing going at us. He shot it before we crossed the tube but still...it's a dove...not your last meal on earth.
Anyway, we got close enough to the safflower fields to be where doves were flying but far enough away where we wouldn't have our skin broken if we got shot. Typical public land dove season standard. My friend shot 7 doves and I shot one. #7 steel shot and IC/Mod tubes is not the setup in 20 ga. The doves avoided any tule clumps and flew down the mowed grass strips giving 30-40 yd shots. Too far for me. Some guys had robo doves out and I didn't see it made any difference. I saw one guy with at least two dozen dove decoys and a flapper who apparently shot his limit. Decoys work better than the flapper for doves in my experience.
The sound of those low base shells aimed pretty much at me was overpowering. It was painful for me and I have damaged hearing. My last opening day on a public area.
Beniciahd check to see if you need steel at Knoxville. I'm pretty sure you do on any state owned land. A warden was out on the area we hunted. If you had it, cool. If not, it's a change this year.
