I feel like they didn't even put out the 2 1/8 oz loads this year and I didn't even see any last year either, I too could not find ANY. I luckily got two boxes last year that a guy had been holding for two years and had switched to TSS so those will hold me over for awhile. My gun shoots ridiculously good with the 2 1/8 oz #5 but just pretty good with 2 oz #5. My gun hates the 6's in everything but RoosterXR 2 3/4" but would pass with 4's in most their options if that was all that I had to shoot. That being said I'm right there with you, those 3 1/2" 2 1/8oz #5's are one of the best turkey shells on the market,
I wish you luck in your search and if you find a whole case or more than you need, I'll split it with you.
