George, they do have the same bolt face but according to Jim Kobe:
"If you go with the fireball, you will need a fireball action. The ejector pin is repositioed to eliminate ejector problems. If you use a standard 223 action, on ejection, the case will drop off and stay in the loading port"
I am leaning towards a Rem 700 but am open to whatever comes on the used market at a good price. Who knows, this might be a good excuse to purchase another Cooper:) Or I might get lucky and find one of the lefty Rem 700's built in 17 Fireball.
