Ken,
I got both of the 10 inch Contender bull barrels in the Herrett calibers about 30 years ago. I do not remember the year now they had only been out a few months and they both came with loading data that included Bob's address and phone number. I was having a problems with the .30 Herrett and picked up the phone and gave Bob a call. As I recall it rang a couple of times and he answered and we spent 30 minutes discussing the fine points of accuracy with the .30 and .357 Herretts cartridges. I spent that evening loading the and following his directions. He was dead on, the five or six inch groups went to 1 to 2 inches. A few days later he gave me a call to see how the groups were going. That was really nice, I was nothing but a kid in college at that time and he knew that, but he still called to check on me. I have taken quite a few deer and hogs with the Herrett calibers now, but every time I take one of them out I remember that Bob Milek cared enough to help me.
Take care!
Marcus
