I am currently sitting at a base to ogive measurement of 1.654" on my loads. My base to ogive to hit the lands is 1.748". That gives me a current bullet jump of 0.094".
When I settled on my powder charge (26.96gr IMR8208xbr). My SD numbers are single digits and I have no pressure signs. When I did my length tests I started at 1.626 and ran it to 1.686". I settled on my measurement bringing me down from 1.5moa to 3/4moa.
Have to agree myself. I thinking playing with seating depth in increments of 5 thousands is a good thing.
Both my 12.5 and 12 inch grendels 120 gold dot load shoot well inside 5 shots under half inch because of doing a good ladder and then playing with seating depth till I found what it wanted.
Realistically the argument that a bolt action grendel has more room for loads is just that a argument. I have owned a howa grendel and now a CZ grendel and the difference in useable mag space isn't enough to say it's a difference.
My thinking is if I do something for my bolt grendel handloads too get the most out of them, then why would I not use those same techniques when loading for my ar grendels.
