Geno,
Another possibility that occurred to me is paper-patching the .243 Cutting Edge 55-grain Raptor bullet. The Raptors are brass bullets that have a big hollow-point on one end and a flat nose on the other, so can be used either as expanding or solid bullets simply be reversing them. (The hollow-point can also be filled with a press-in plastic tip to increase BC, but that wouldn't apply here.) They're supposed to expand down to 1500 fps, and the 55 just might stabilize. If you're interested, I could send you a few if you'd like to try.
Cutting Edge also makes a 70-grain .257 Raptor but it probably wouldn't stabilize in the twists of your rifles. But the 55 .243 might, according to the old Greenhill Formula, which is more appropriate for blunt bullets at moderate velocities than the modern computer formulas, which are primarily designed for very long and streamlined high-BC bottails.
