Interesting article by Armbrust.
It reads like an ad for modern components.
Modern components are indeed very good, but...
Only one powder was tested.
Only light target loads were tested.
The concluding comments about weak crimps and field loads with slower powders while traditional common wisdom and undoubtedly correct is not supported at all by his data in the article! He didn't test any!
This whole waste of ink is ONE data point about American Select which is a good powder but hardly universally used. It's not the most cost effective powder, thus has not captured a dominant market share.
I would not extrapolate this to other powders, especially anything with slower 'relative quickness' like Green Dot, Universal, etc.
