One of the best groups I have shot with your old Ackley was with the Berger VLDs and new hydraulically formed brass with a less than perfect forming, (still had rounded shoulder) a tiny shoulder bump. Projectiles jammed into lands to ensure base is snug against bolt face. ES wasnt flash but the groups were.
Didn't worry too much about seating after that as it just shoots with acceptable ES when you do your bit it seems, wherever they're seated.
My blaser 260 ackley uses the exact same load. Also not fussy on seating. Same speed and group sizes with identical ES however the fired brass cannot be interchanged.
Shot both for the first time since before lockdown yesterday. Both shot way better than I expected as I havent fired anything but my pistols and shotgun since March. Wish I could shoot my pistols and shotguns as competently as I do my rifles after a long break.
