Quite a few years ago I bought two cases of the Seller & Bellot 12ga "OO" Buck 9 pellet.
It was faster but the tradeoff was the load density.
It patterned ok thru my Pattern Master tube but seemed too tight. Even thru a modified tube. It cycled good in both my Benelli and my 11-87. The hulls were "throw away".
I have not shot any of this brand. --- SAWMAN
