So I been researching what choke you should use for trap and really don't get any solid answers. Anyone have any advice on choke selection?

I just bought an Win SX3 and used it for a trapshoot fundraiser, and I shot 33 of 50 (30 mph crosswinds may contributed), but it seemed a lot of my misses should have been hits. I was using a full choke at 16 and 22 yards. I shot equaly at both distances.

Any advice?
