Sorry to hear about losing your Dad wrenchman.
I'm in shotgun zone . . . so hunting with Remy 870. Have to admit, it shoots like a rifle, especially for the Michigan woods where distances are a short range affair.
. . . But, would prefer to use my Heym 26b double, over/under 8x57. Here's a pic of it from when I picked it up from the Heym Factory in Germany. Has quick detach mounts for using either a Docter Red Dot or a Scope
