I've had the same problem with 50's - 60's Chickerings. I think it is because 
they use a very high tension scale. While the tension on most pianos strings 
are at about 50% to 70% of breaking, I think the Chickerings are at about 90 
- 95% of breaking.

The only way to bring a piano like that up to pitch is to bring only up to 
pitch, but do it several times, until it stays.

Good luck
