I mentioned the not-to-long-ago world record 1000 yd here not too long ago. I left out the fact that the group of less than 1.5" was in fact the 3rd group for the shooter in that match. First was 9.something", then 4.oranother" before the record breaker was recorded. Sad to say, two out of three of those groups might not have hit a hoof at that range, least not with all the shots...on purpose. That .300 Win Mag may not be up to the task. Of course it wasn't a Ruger so you just never know.
