243-8 twist

[lonestardiver]

I'm getting a 26" 243 8 twist barrel and need some advice on how heavy a bullet can I use.
Thanks

Barrel twist determines how long of a bullet it will stabilize.
A longer bullet requires a faster twist than a shorter bullet.
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.
