Considering the experiment has produced favorable results at this point in time, I think you are onto to something. But in terms of ever suggesting that anyone having steel cases reload and use them on a regular basis, I'm not so sure that would send the right message, especially to newer less experienced reloaders.
However, if the left side continues to impede on our shooting sports, including reloading, tests such as this can provide alternative methods of using alternative components if things should ever reach a critical point. And considering that assault weapons, as they like to label AR's and other weapons of similar function and design, are receiving some serious attention that may eventually lead to the restriction or elimination of ammunition, and limited component availability. In other words, you just never know what's to come down the road, or how bad it will effect us as reloaders and sportsmen.
Good post, and definitely good food for thought!
