The 1 in 7 will in all probability like ammunition around the 62-69+ grain area for max accuracy. Although it will also shoot the 55s OK but you will probably not get max accuracy with the lighter bullets due to the faster twist. To check out their max accuracy I would suggest Federal Gold Medal or Black Hills BT HP Match. For just shooting and still with accuracy you might look at American Eagle or Winchester White Box. Both are FMJs.

America will never be destroyed from the outside. If we falter and lose our freedoms, it will be because we destroyed ourselves.
