ELD bullets can be longer then their same weighted conventional bullets and may require a faster twist.

A lot of this is seen in the 5.56/.223 realm with the steel core 62gr bullets. Being they are less dense than a mostly lead bullet so they are longer...and require a faster twist barrel to spin them fast enough to stabilize.

If I may add to this good advice. A bullet with a larger bearing surface requires a faster twist. Bearing surface is the operative term. Bullet length obviously has an affect on bearing surface, but it's not the driving variable.

I believe the Berger VLD Hunter bullets are a good example of this concept. The bullet is long, but the bearing surface is small.
