Grand powder and the .270 150 Grain Ballistic Tip

[trapper10]

Can anyone provide me with QL data for Grand Powder?

I do not have quickload but Hodgon reloading data suggest starting charge of 57 grains with a max charge of 61.6 grains for a 150 grain hornady bullet. I am betting if you stay within those parameters you will be fine.

I used grand with a 150 Partition, my load ended up being 62.0 grs with a magnum primer. The deviations were large using regular rifle primers. I did a ladder test starting at 57.5 and working up.

Grand very close to H1000 in burn rate !
In 270 Win would it outperform H4831 or Reloader 22

What velocities did you get in your ladder test

I burned up a pound of Grand while testing in various cartridges. In my tests, Grand proved to have a burn rate very close to Retumbo. It was slower burning than H1000 in all of my tests. I used Fed 215M primers in all of my tests.
