Having reloaded for close to 50 years, like Dirtfarmer, I used Herter's then RCBS,. However, I never found a reason to start switching.I do have a set of Lee dies for a 38-40, but aside from that all the die boxes are green. A person can't beat that RCBS customer service
I did lot of competition shooting in the 80's and never had an occasion where an more expensive set of dies would have made the difference in my scores or in the killing of deer,elk, and pronghorn
