The RCBS Gold Medal Seating Die does have a sleeve that comes down the shoulder and comes down on the case body about .425". The seating spindle is also floating. Those are the 2 differences from the RCBS Competition Seating Die.
I have 1 of the Gold Medal kind in 300 win mag, 5 of the Competition Seaters (22-250, 6.5x55, 270, 7 mag & 30-06) and 2 of the Redding Competition Seaters (280AI & 338).
Putting the bullet in the side is very convenient and the bullet is held in line with the case body and neck from the beginning of the seating process. Setting the bullet on top of the case and raising up into the die it starts canted. The Redding Competition Seaters have a collet to realign the bullet but it is not as convenient.
All of these seaters seat to the same amount of variation as measured by comparator after each seating. I can detect no induced runout from any of them.
If I need another I will try to get the RCBS Competition Seater because it is cheaper than the Gold Medal and appears to do just as good a job. JMHO
