That makes sense! I haven't done any precision type shooting more than my AR iron sights at 200yds, but have been really interested in getting a Rem700 (quite a ways off though) to start getting into the long range game. Thanks for the tip!
Yea, I have a thumbhole stock on my Savage Mark II-FV and find when I'm going for a string of shots as fast as possible, I don't insert my thumb which is no different from wrapping it around a grip really.
