Here's a link to a short video:

5 Shots
1000 yards
Savage BA110
IMR 7977 89.5grns
2750 fps
Calm winds
80 degrees

First shot at 4 foot stop sign...

next 4 shots at 1 ft tall Prairie Dog...

Looks like about a 1 MOA grouping.

This rifle seems to prefer 300 SMK and 250 SMK.

250 Lapua Scenars still string vertically from top to bottom of the Stop sign.

Heres' the youtube video..
