Hornady has always been pretty good about such things. We've stopped by their plant on two occasions, without any appointments or anything, and gotten plant tours, they were very accommodating, regarding such things. We had a fun time with their range techs, and looking over their test range. I was pretty happy (at the time) to see the machine making V-Max bullets spitting out a bullet about every 2/3s of a second. IIRC, they said they could make 50,000 a day with one machine! We were always coming back from a prairie dog shoot or something when we stopped in.
I've been to the Sierra plant in Sedalia MO, a time or three, also, both companies are very good to visitors just stopping by.
