The 1:7 is perfect for an AR in my opinion. it will shoot anything from 50-90 gr bullets just fine.

The Army uses the Mann Accuracy Device to test their ammo. They use 52 Gr SMK loads as a control. The Mann Device is a 1:7.

Only problem you'll have is using light 40 gr bullets for the Hornet and Hornet velocities.
