groups at 400 yards

[skb2706]

Best way to find out........set up your 100 yd target at 400 yds. Shoot it and see. It will be exactly four times harder to see....that part is linear. Add in the fact that the bullet will be in flight longer, the drop is parabolic and your optics that work great at 100 yds. fail miserably at 400 yds. You would be extremely lucky to get linear results.
