I did finish my testing with the 64 gr BSB in both the 223 and the 220. In the 223 the powder that finally worked was H335, and I didn't get good groups till I got close to max loads. Then I got great groupings. In the 220 I decided to stay with good old dependable IMR 4064. The bullet did stabilize, which was a pleasant surprise, but like in the 223 the groups were nothing special until I got right to max. Then the bullet shot great.

Even better, the bullet in the 223 prints only slightly above the POI of the 40 gr Nosler BT that I usually shoot in the rifle. No sight changes needed.

One thing left to do is to wait for cold weather and see if that causes any problem with stabilizing the bullet in my 220.
