Has anyone here tried this bullet? If so, what were
your results? Did you need to seat them to/into the
lands for accuracy?

I would be particularly interested in hearing from
anyone using them in a 7mm WSM cartridge as well.

Here is about as good of an answer as I can get ya. It comes from Berger themselves along with some other great info.
