At one point I had a Lee Load-all for 16 ga. I never could get decent loads out of it. I later bought a Mec 600, which has the capability of being adjusted. I ended up finding out that the best wads for the cases that I could find were those sold by BPI (Ballistic Products Inc). They sell an amazing variety of shotshell components, including wads and hulls for nearly every gauge. They also sell a pretty complete book of loading data specifically for the 16. While working with the 16, I found that once-fired Winchester low-brass hulls were good for only a couple of reloads before splitting, but the BPI wads worked well in them. I once bought a bag of 16 ga Remington wads--the only American ones I could find. These never worked well in anything--not even in Remington hulls!! Somewhere in my loading area I still have the better part of a bag of these, and would part with them for the cost of shipping to anyone who wants them, with my best wishes. I still have my Mec, and load for a Baikal side-by-side. Nice gun. If I were starting out on this gauge, I'd get a Mec press from the beginning, and buy fresh wads and hulls from the BPI catalog.
