    Was wondering what all calibers I can use them for. I have a few of them and reloaded my 7mag and 300wm with and was wondering if I could use them on anything else 6.5x284, 270w, 243w, etc ?

    You can use them for any case that needs a large rifle primer. You just need to start low with the powder and work your way up watching for pressure signs. About all ball powders recommend using Mag primers.
