Well, I finally remembered to email the folks at Hornady and ask them why they suspended what I feel was one of their absolute TOP performing bullets in the lineup. Especially in .308 and .284 diameters. Here is their reply:
Thank you for your email. We originally suspended this line due to the overwhelming spike in demand several years ago. The process to make this particular line is very time consuming to say the least and we were focusing our energies on making more of the higher demand items at that time to better help us attempt to keep up with the tremendous spike in demand. We had a very hard decision to make during this time and decided to suspend the production of many items that just weren’t selling as well throughout this time of dramatically increased sales. We are very sorry for any inconvenience this has caused. We hope to get this put back into the line at some point but we just can’t tell you when, right now. We appreciate your support and your patience with us.
I'm guessing the "spike" was in "defense" bullet lines and us hunters took a back seat as usual.
