You are confused..."if faster twist rate mean you can fire heavy and light bullet"
Generally speaking, the heavier the bullet in a given caliber, the faster the rate of twist required to stabilize the bullet. For instance, look at the Berger website
Berger Hunting Bullets
If you just look at the 6mm bullets you will see they manufacture 95, 105 and 115 grain bullets. 1:9 recommended for 95, 1:8 for 105 and 1:7 for 115.
Also generally speaking, when choosing your twist rate, you want to choose a rate that is appropriate for the heaviest bullet you plan to shoot.
