Impressive stuff there. 400yds is a LOOOONNNNNGGGG way. Bronko is right...shot #1 is what really counts. Good shooting man, awesome. Those CDS dials sure are something, I'll say. I personally at this time have no use for one...but you've proven they are worth it for long range use.

How far off was your velocity?

(oh, and once you peel the target from your stand...that's an amazing 400yd group! )
