This is what I do in combination with quickload. This is a outline I created of Erik Cortina's process that I created for my brother. If you go to his YT you can listen to it, I highly suggest it. I have been reloading for 20 or so years and wish I had this when I started. It does require an accurate scale to be effective and if you don't anneal I would start. Hope it helps. Randy
Step 1 Combustion
Combustion is Extreme Spread (ES)
Find powder with low ES
Bad ES
Wrong powder charge
Wrong powder type
Wrong powder
Case capacity variant
Wrong Neck tension
GOOD ES go to step 2
Step 2 = Harmonics (Group Size)
Good ES but bad group = bad harmonics, ie seating depth
Adjust seating depth
Find jam and subtract 20 thousandths (0.020)
Adjust three thousandths increments (0.003)
Find seating depths that give consecutive good groups
x- 2.150, 2.153, 2.156 are good groups
Pick 2.155 as depth
Seat 2.158
Every once in a while to check if it will shoot Or if groups opens up
Step 3 Ext. ballistics
Group at 100 is but group sucks at distance
Bullet BC may be inconsistent
Change bullet
In a nut shell
Find low es
Then seating for group
High es = adjust step one
Low es adjust seating
Reshoot for velocity
