I am currently shooting a Benelli Field M2, with hevi shot crio choke. The pattern is decent, but i want better. I am looking to improve my gun by adding a burris speed bead and a new choke. I am sitting on a ton of Magnum Blend that i acquired at a steal, so i am wondering if someone can point me in the right direction for the best choke for this combination of gun and ammo. I tried to search on here myself for the answer, but clearly i am missing the right combination of words
