So I loaded some and tried the shake down method. Saw another version of it, by taking a tray that holds the brass, load the charge (I did 3, CFE 223, A2520, Varget), then put another tray upside down, on top to hold everything in place. Laid on an oscillator tool for 5 seconds or so.
This used max Hornady load data on a 129g SST.
All shook down so there was no more compression when seating the bullet. Shake down was in the range of .040 to .060.
I am going to the range in the next day.
So, with this shake down, would it be considered compression? We are certainly removing the small gaps.
At least, I have refrained from crunching the power when loading the round.
Thanks for the feedback.
