I tried them and they shot pretty well, after I worked up a load for them, with CFE 223 in a couple of my 20 calibers. However I passed them onto another party on this site, as I am switching over to all non-lead, with Nosler and Hornady, due to my commie state going non-lead in July-2019.
Think you will like them, they compare well to the Sierra 39 grain. Bill K
