You didn't tell us what your shooting goals are.
If I wanted to go shoot with
@Alex Wheeler at a match and pretend to be halfway competitive, yeah I'd look at better dies.
Note, I'd love to shoot at a match with Mr. Wheeler, but I know better than to think I would be competitive with him!
The dies I have for my 7mm-08AI are old Pacific dies I found a flea market for $15.
I have hit a 24X24" steel plate at 1,300 yards. Took it to shoot my first F-Open match (600 yards).
So, no. You might not need to get the top notch dies.
