Berger seating depth test and changing powders

[letrbuck]

Since the Berger VLD test is all about finding the right seating depth, changing powder shouldn't cause big changes right? I'm about to start load development in my 280 rem (22" barrel) using the 168 VLD. I'm hoping to find a node as close to 2700 as I can, and I have RL 19, RL 22, IMR 7828ssc and H4831. If I test seating depth with RL 19 and dont find an accuracy and velocity combo that I like I should be able to stick with the seating depth and change powder without starting the seating depth test all over right?

Anyone have experience with the 168 in a 280? What was your powder and velocity combo?

Thanks!

From what I've seen, best seating is independent of powder.
I would not change seating for powder changes.
