Second for the CMM Ultimate Brass Catcher. It is all I see when competing in the local Bullseye events. A good idea is a c-clamp to hold it on the bench in the wind. The standard unit can adjust to cover just about anything coming out of my pistols. It also saves a lot of clean up time, even with 22's, and I think it leads to higher scores since the person next to you hasn't been dodging hot brass before going out to score your target.
Mine has actually caught brass on the outside of the net. Really.
