With all the new shooters, all of a sudden and those getting started in handloading, this should clear up seating depth problems, you might have or not be aware of. I figured this out long ago when I bought a factory Rem LR 300 RUM, with it's long throat and standard magazine length, which is the jam length, and I was only able to go away from the lands, to remain mag fed, to find the rifle's optimum seating depth node.
EC explains this better on a video than I could on paper, without writing a chapter on it! I just recalled this from when he put it up, as I'm just now getting around to starting load development on another 28 Nosler barrel and thought other's might find it handy.
I have never chased the lands. Wore out a 7STW barrel and never adjusted seating depth, once I found the node and it still grouped with a throat that would make a Weatherby fan boi green with envy. Only reason it got replaced it was, I couldn't make new 7STW brass for it (300 WB necked to 7mm).
This ain't F-Class, but you can learn a lot from it!
