I've used all three with 4.0 gr. of Bullseye. The Bayou TCG is my favorite, as it best combines low smoke, easy of loading (1050 + Mr. Bulletfeeder), and accuracy. The SNS RN also loads real smooth but smokes more and may not be quite as accurate. But it's cheaper, and I've been shooting them a lot lately. I couldn't get the BBIs to load smoothly in my setup—very tippy during indexing. YMMV.
