fps for 220 gr '06 at 100yds?

The problem with using a 220 grn bullet in 30-06 is that most rifles won't stabilize them. A bullet that heavy in .30 cal really needs a 1 in 8 twist (or at least a 1 in 9).

Not sure about that. The Army went to the 1:10 in the Krag and Springfield because it does in fact stabilize the 220 RN bullet.

In fact that was the bullet used in Gen Hatchers example explaining twist, in his "Hatcher's Notebook".
 
Twist

Also not sure about that need for a faster than 1-10 twist.
For a while, I experimented with the Barnes 250 grain RNSP in .308" dia.. A very long gullet. I do not recall any accuracy problems with 1-10 barrels.
 
Berger bullets says recommended twist rate for a 230 grain VLD boat tail is 1:10in. Bullet length is listed as 1.64'' which is probably the longest bullet you can use in 1:10in twist barrels.
 
The 165 gr Barnes bullet is in every way superior to a 220 gr load in 30-06. Superior ballistics, penetration, and terminal performance. The late Greg Rodriguez wrote an article on the subject

this isn't ging to be used for animals with thin hides and small bone structures. this is for AFRICAN GAME, thick hides, thicker muscle tissue and heavy bone wreaks havoc on lighter bullets traveling at high speeds. a heavy round nose traveling slower is better because even though it's slower and doesn't expand as much it takes more to stop it.
