My huntin pardner is working or has been working with them some. Here is a plate we got hanging at 500yds, that has a few impacts from the Bergers on it, for what it's worth. The plate is a scrapped 12"- 150# blind, the white circle is 2.5" in dia. These weren't shot in ideal conditions by any means. 15+ mph winds coming in from 3 on the first one and from 9 on the second.
This is both Bergers and Wildcat 210's,
This one is just showing the Bergers.
If I can get the data from him I will post it up or maybe he will when he gets off work. I know that mostly he is using H-1000 and Retumbo.
