Re: what reloading dies to get for 7mm RUM
I've never used RCBS, but I love my forester dies and redding dies. I really like my forester seater with the micrometer top. They are less than the Redding and just as good. In fact I like the forester lock nut better since it does not go into the threads. Hornady make the same type of lock nuts, but with an allen head instead of foresters philips head screw. No matter what dies you go with, pick up some hornady or forester rings, you dont want to damage the threads.
I really think the micrometer top is great when seating bullets, you get .001 with every hash mark. It beats messing with the die every time.
Good luck with whatever you chose!
