Made it out today to do little load testing on a sub zero -1 deg this evening withe 90 gr CX over 30.9 grains CFE 223. While I was not surprised results were less than stellar in terms of velocity spread. 5 shot string gave a velocity spread from 2860 1st cold bore shot to 2931. This was with a Rem 7.5 primer & Starling brass.
If i omit the 1st shot then the speed ranges from 2899 to 2931.
Was unsuccessful for the 2nd time trying to capture a bullet at the end of a series of water jugs. grr
Will try a similar test on a warmer day
