To those who say "you have to remain supersonic to consistently hit at 1000 yards" I give you this:

200 yard group for reference: http://imgur.com/MNOawmh 1000 yards factory ammo 5 shot group: http://imgur.com/fAVHyWZ http://imgur.com/EaJ2ANx

The fgm 175 smk is well into the subsonic range at 1000 yards.

Considering I'm still learning how to properly read wind and I didn't bring a sporting scope (shot 5, drove down, checked, drove back adjusted) I consider this impressive considering everything I had read online up to this moment about the topic.
