I have owned two 30-06 Ackley rifles. The first was from PO himself, the second by Bevan King. Both were very accurate, and both got 180s a bit over 2900 fps out of 24" barrels with good case life and tight primer pockets after five loads.
That said, I have neither rifle today. No particular reason, other than the one from the old man himself sold for too much money, and the other went down the road and wa just never replaced.
