    Hi Jim

    What software did you use to determine the pressure of that scenario?

    I'm looking for something that will calculate these numbers for me.

    Thanks!

    Idon't need that kind of speed or pressure but that group is the best.
    Started at 93grains and worked up.It's not showing any signs of pressure.
    What would you do?

    Definitely shoot over a chrony to see what the bullet is really doing. There are so many variables to consider that speculation is not a good place to be.

    I have not used Quickload before, but when I shoot an accurate load, even when I think it may be hot, over my chrony, I find that my velocities are actually within the safe realm.

    Powder variances from the lot the book was tested at to elevation to barrel twist and length all contribute to what the reality for your gun is.
