I needed some new brass for my .270 Short Mag and purchased these because I have had good luck with the Hornady brand. When I received the brass I pulled it out of the package and started to check the sizes with calipers and found that everything was very well inside the specs as well as the brass was round and not bent out of shape. I have been using the brass now for over a year, they are on the third load and I don't see any signs of malfunction or possible failure. They have all stayed relative uniform and I have not had a single problem with loading malfuction or misfires.
