I can not dispute what you say. I am not into shooting targets only in as much as I look for a good accurate load to hunt with in my guns and do not check my brass to the level some do.
Having said that then I guess I can't explain why when using average/normal reloading practices, I have found loads using Hornady brass that have given me moa or better results in three different rifles.
Not trying to be confrontational, just trying to understand and maybe learn a little something.
What kind of accuracy have you been able to obtain on 1st loading as opposed to once fired?
