Will Redding's or Forester's BR seaters work with cast bullets?

I want to load my 7BR XP-100 with cast bullets as accurately as I can, and was wondering if the BR style seaters from Redding and Forester works for cast bullets. Thanks-

I use the Redding 45-70 BR Michrometer seating die with my 45-90 and lead pills so why not?
