Yes I did pattern them, come to find out I shot several of them last year hunting with my friend, matter of fact I got a double on the last day of season with these same shells out of my browning gold. I would have never remembered the name of them if I hadn't talked to him today. As for shot size, I always shoot BB, or BBB all year round because I buy my shells by the case and a case will last me all season. One of the cases I bought today is for my brother in law, he shot some with us last year and liked them as well through his bps.
