Those load work up notes speak the language of my people.....
Would that be 1-shot velocity plateau/node workups?
Not my language, but the 52.3 gr load seemed to work decent. Would certainly be interesting to see what 51.8 and 52.8 loads do for 3-sht groups.
A lot got taken out of context, or misunderstood, in previous threads, and I'm not in the mood to go over it again.
But yeah, I have lots of notes that look just like that. That's where I'd start looking pretty close for a load, right there around the middle of those velocities if it's near the top end of the load parameters. Just finding a starting point to work from. With a 7-08 I would probably have ran .2 grain increments to get a better initial look at it with that case capacity, but the .3 grain found it quick enough.
