Well I've never checked...here goes. Good grief...no wonder I have no storage space on my shelves. The oldest dies I have are early 60's, Herter's chrome plated in .243 and .222. Good dies too. I've also accumulated Lyman, Redding, RCBS, Lee and Dillon dies as well. Given a choice, and if it's your $ we're spending I'd pick RCBS for rifle and Dillon for handgun. Some here damn Lee's dies but I've never had a problem with them and loaded ammunition for both Rifle and Handgun every bit as accurate as more expensive dies. For Seating match loads, I really like the Micrometer ones...mine are Redding (I think?) Rod
