    MJS,

    Have you done any further development in the last decade?

    I prefer to use cartridges born before I was.

    Gary,

    Not at all. We come here to share what we know and learn what we don’t know. You have a lot to share!

    I load a 275 from hunter's supply with Bluedot in my 7" Longslide and get around 1000fps.
    I do have a heavier spring. The cases tumble out at my feet. I don't think I'm running it too hard. I'm not going to shoot them in my Star PD
