It seems like all the new bonded bullets designed for expansion have a larger surface area at the meplat. I think it might be required for expansion. If the bullet had a higher bc it might not expand.
With a bc of .25 at 2750fps you will be above 1800fps out to 300 yards. Depending on environmental conditions that might be able to be extended by a little. Having a bullet that expands out to 300 is pretty good.
Edit: when i wrote that i was not thinking clearly. They do have a 75 grain swift scirocco II in 224 diameter. I do not know if anyone loads it in commercial ammo, but it is available as a component. It should fit all the requirements you were looking for. The only thing is it does not have a solid base. It is a boat tail, ballistic tip, bonded, hunting bullet that looks to have a good ballistic coefficient. They cost about the same as other high end bonded bullets. I have seen them for about .40-.50¢ a piece. I always forget about it. I need to pick some up it could replace a lot of bullets i load.
