So I recently bought a savage based rifle with a Shilen 7mm mag barrel on it. Supposedly it will shoot 4-4.5" groups at 1k if the shooter does their part. I put a Leupold vx3 8.5-25 lr scope on it in Burris Signature rings and sighted it in at about 40 yards since that's the farthest I have currently available. I used the rounds that came with the rifle, but it shoots about 2". I talked to the PO and he told me that I need to shoot a minimum of 150 yards to allow the bullet to stabilize. Does that sound right? Every other rifle I have will easily outshoot this one at this range. I always thought the farther distance you shot at, your groups would widen.
