Best bet might be a round or flat nose design intended for the .30-30. They would be expected to expand at those decreased velocities. If you are looking for something more aerodynamic, look at the plastic tipped spitzers from just about every maker. Their design makes expansion at reduced velocities much more positive.
In life, strive to take the high road....It offers a better field of fire.
