Road to Precision video

I viewed most of the Road to Precision videos (link below) and found some interesting ideas that might relate to bullseye.  There are over 20 videos and they tend to be long but are well done.  Kudos to the guy that took the time and effort to put his thoughts and experiences together.

Here are a few of the things I found interesting in the videos.

Differentiating accuracy from precision.  Defined in 1st video.
Dramatic results from small powder changes
Methodical approach to improving shooting skills
Practical realization at final segment
