Doc--I would only be guessing at what load he is using. I
THINK, not KNOW, he is using 25.0 gr. of Reloder 10X, but I'm not sure. He may have listed the load he is using over on the Predator Masters Board or over at the Ruger Hunting Board. His board name is Howler.
Check out the load data that Hodgdon has listed for the 40 gr. V-Max and work with those powder charges. I use a stiff load of H4895 for my 39 gr. Sierra BK load for my Savage 12VLP. If you decide to use H4895, please start well under the load I have listed on these targets and work up slowly--like no more than .2 of a grain at a time. Here are two 3-shot groups I did while testing this load and below them is a 5-shot group I did to make sure the load would give me the same accuracy with 5 shots that I was getting with just 3 shots. Obviously, I am no benchrest shooter. Whenever I have a small 3-shot group started, I
ALWAYS mess it up by shooting shot 4 or shot 5.
