Well, I used Harrell's for my bushing sizing die, but that was before I knew about Whidden's. Harrell's was "The Thing" back in the 90's when I got into the 30BR. Still think they make a quality product at a very favorable price point. I have a couple of Whidden's dies, too, and think they are great. You can't beat the customer service from either place. If you are having your rifle chambered with the "Robinett" reamer, save yourself some money and get a Harrell's. If you have a more customized chamber, Whidden would probably be a better choice.
