That's the crazy part. There's one in the top that comes from the lower group and vice versa.OH! I am assuming the higher 3 holes belong to 57gn ?

I don't let my barrel get that hot. I might shoot 2 rds first off a cold barrel after that I consider it hot. Reloading is about consistency. Barrel temp also. As close as reasonable. Take more time between shots letting the barrel cool. I try and let my barrel get very cool again. I carry a fan. After all, while developing a hunting load I'm gonna shoot from a cold barrel. I need to know where that round is going. Your doing fine. Keep working upwards.The first group feed from the mag and the second group was done single shot. Probably 10 to 15 seconds between each shot in the 2 different groups. The 2 different groups probably had 10 min between them
I start with seating first.
I've done it both ways, and doing a seating depth test first always gets me to where I need to be. Then I work up to max charge.
Check out Bergers seating depth test. It works with any bullet.
I've loaded for several wby also. Start at magazine length and work powder up. Then if the accuracy not quite there bump bullet back .02" increments and see if the group tightens. If it does then work around that in .005" increments.I have several Weatherbyhunting rifles that I've started loading for
My understanding is that they have increased frrr bore so that the bullet gets a "head start " or jump before entering the lands. It also is supposedly safer because pressures aren't as high.
How do you adjust bullet seating depth in this circumstance? Does it pay to bother with this design?

They will respond to seating depth with some bullets and often will shoot best at saami length. But there's no point with measuring lands. I've also found the heavier for cal bullets work better in wby. I believe they make the jump with yawing better
I do a ten round pressure test to find the max safe pressure and charge weight flat spots for low ES and SD numbers. Here is an example
