Forster die compatibility 7 saum…

[Felton]

I’m putting together a 7 saum and ran across what I thought was a Forster 7 saum micro seater die and purchased it. It was 7 rum
. What are my options here? Could I use a 270 wsm forester benchrest die body with the 7mm seating head or do I need the saum body?

Does any want to trade their 7 saum Forster micro seating die for a 7 rem ultra mag die?

An option is to call Forster and buy just the chamber portion of the seater die for a 7 SAUM. It is reasonably inexpensive and you may have it sooner than looking for a trade.
As for the 270 wsm, the answer is no. The seating plug for a 7mm will not go through the hole in the die chamber, plus the 7mm case neck will also stick in the 270 seating chamber.
