Update: my order was placed in May and I received my case of #6 shells about 2 weeks ago.
Feedback so far- I only shot a couple of shells out of my Arrieta sxs and for low pressure they sure had some strong recoil. Comparable to 2 3/4 #6 that I have shot. That may have been a bad test as I had already been shooting low pressure 980 #8s at trap so may have skewed my senses. They broke the target no problem.

Only other feedback is the shell boxes fall apart from the bottom with even light handling.
