Recently I bought several boxes of factory 35 Rem. Sale also included a box of reloads marked "No Good". I believed who ever marked them and tore them down. Managed to destroy two cases before I went to a kenitic puller. I now have 18 primed cases to reload, probably with cast. Question is what do I do to the cases? Neck size or full length size. These will be shot in a Remington Model 8. I have not tried to run the cases through my gun. which I probably should do and not ask silly questions. Any thoughts?
