I always rj. Things through QuickLOAD and GRT… then step down from max in .2gr increments in 10 steps. Usually, I always find a good speed (low ES & SD) and no signs of pressure load.
From there I do seating depth testing the same way, I start at .015 off the lands and then move back in .003 increments. Same story as speed testing, the target will show a wave pattern and thats where I find the seating depth window. From there adjust forward .003 when the accuracy drops off from barrel erosion.
Total transparency, I used to over complicate things and also teetered on the edge of danger. Best advice I can give anyone is read, watch videos and learn. When you practice what you learned, proceed with extreme caution until you build knowledge of your own rifle and with that comes confidence. This can be a very rewarding fun hobby but can also be your worst nightmare if you don’t humble yourself and pay close attention what you’re doing and end result thereof… Happy Shooting Everyone!
Btw.. Here’s my final seating depth test on the Berger 85.5gr LRHT #22785. These things seem to perform great in my rifle. These were shot off a Harris Bipod with Hawk Hill spike feet and an Armageddon Schmedium rear bag and some patience.. LoL
