Yep. These article and quotations appear in Zeglin's book. The 25/35 is on the top PO's list of most improved cartridges. This could be because factory load were anemic and the AI loads are loaded to to SAMMI pressure. Only a guess. The picture address whether PO actually tested things for himself. I also have no doubt that data was submitted to him as well.

At any rate, my Stevens .30/30 bolt gun will be back in my hands in a week or so. Then can start testing and reporting what I see.
