A lot of good reloading information available from 3 a times national benchrest champion, Bruce Teel
and Brian Zonlnikov.
I laughed when I saw the target from Bruce's powder charge tests which are at 600 yards - his worst 600 yard dispersion is my better 100 meter shooting.
From Brian, you gain an understanding of what technicality really matters, and most importantly from both these knowledge sharers, how much it matters.
As reloaders, we understand the general concept that everything matters. What these two men show us is how much different things actually matter.
After watching a few of Bruce's videos, I realised that he video recorded all the steps that he took to help him arrive at national champion, and shared it with whoever is interested. This is unique amongst champion shooters.
