6.5-284.
Mine is only a few years old. I also like it because I got a smoking deal on 300 pieces of Norma brass and still bought 200 pieces of Lapua brass the same week because it was priced lower than I'd ever seen it.
That said, better take a good look at the 6.5 Sherman. Had I known about it, I would have likely gone that route and used Norma brass. In fact, I have an older 7mag that I've done very well with over the years, that I'm going to sell just to make room for the Sherman.
