idaho,
Fantastic post. Thank you for taking the time to type that out.
Blaze,
idaho is a no bullshit S.M.E. with regards to teaching and application here, so it would be wise to listen to him.
mapwhap also has a ton of experience not just shooting, but teaching so if he gets back in here I would pay extra attention there as well.
With respect to the recommended books.
I love Cooper’s Principles.
If you can find the Bill Jordan book for an affordable price get it.
The Enos book is fantastic, but it is really Zen in the Art of Putting Metal Through Your Target. I would buy it, but depending on where your skill development is you might want to shelve it, or breeze through it the first read. It is something that can be re-read every year and new things learned/pondered.
Here is another thread I started a year ago, with an article I really like for teaching the de-facto standard Enos/Leatham thumbs forward grip.
The thread also has some great information from idaho and WN76.
Hope this helped.
Regards,
Robert A
