Does base of the slug effects accuracy?

[Airmanator]

I've only been shooting flat base nsa slug in 25 cal both 33.5gr and 36.2gr. But now I see the new 34.9gr and 38.9gr and they are dish base or have a rounded bottom. And their BC is .110-.115 vs the flat base which is only .100. So are the dish base better than just plain flat base? Why is the BC higher than the flat base?
