What works for me won't necessarily work for you. My experience is not with Grendel but with .308 (Winchester and Federal). When I got into Grendel I went whole hog and got 2k pieces of Hornady brass. What I did do and had to do for my own peace of mind was to work up all new load data for the two different cases. Maybe not start at the beginning but perhaps a grain less and go from there. That may not be what you want to hear, but that is my opinion from my experience. You are clearly not a rookie reloader hence my reply about you knowing what you SHOULD do, not what you want to do. Didn't mean to offend you.
