Since I shoot outdoors at my home, I have always liked Bullseye/WW231 and any W/C I have on hand... Smoke is no concern for me. In my experience, if lowest smoke and cleanliness is desired using a plain lead bullet, Clays and a Swaged Hornady W/C fits the bill. If you substitute a copper plated W/C for plain lead, you will really dial in on what you want.
The type, quantity, and quality of the lube is what will most critically dictate the amount of smoke, so in my experience the Hornady swaged bullets that are dip lubed, then dry coated (mica I think), seem to work best to keep smoke down.
