I was out playing with a 6.5-284 hunting setup at 1200-1351 last month. I was shooting 147eldm at 2940fps. I really like the tally ring/base combo for weight and just to minimize things. At 1200, my hst 6-24 was almost maxed out at 9.1 mils (I zero at 300). At 1350, I was having to hold over 2 full mils! All this to say, the talley RB combo is great, but if you plan on shooting further, you might want a different setup.
