Irregular velocities with 7prc loads

[Idaho Lefty]

Better than "Most" of, the IMR Powders, but probably, Not as "Good" as some of, the very Best, Hogdon Powders,.. like, H-4831, etc.
You might also Try, working Up loads with, F-215 Magnum Primers and, the StaBall HD.
I Use, a LOT of StaBall 65, in my 6.5 Creed and even Here, in Winter at 20 Degrees Above,. NO, Accuracy, "issues" for Me,.. Yet.
My son will Be Testing his 7PRC Loads, in the Next 2-3 Weeks,. Hopefully ( He's got, 50 Loaded / ready to, Go ).

Ive never used Staball H D how is the temp stability of it?t

You Might Try calling, the St Mary's, Florida, Olin / Winchester, Powder Plant and Ask,. that Question.

what part of Idaho are you from?

 

[Idaho Lefty]

The Boise / Meridian,.. area and I Shoot Out, in the Desert towards Mountain Home, when It's Above 20 Degrees and the Wind is Below, 4-5 MPH,.
In fact, I'm Heading Out soon to, Shoot my 6.5 Creed ( Check Zero @ 200 Yds ) and Play with my Marlin .30-30 On, Steel Plates.
