I just bought two of the Redfield Revolution 3-9x40 with the Tac-x retical for my calling rifles. I usually like more magnification but the deal I got on them couldn't be passed up. I've had 1 out once so far, and REALLY like it. On the range, 9x was plenty to explode assorted garden veggies (that didn't ripen in time) at 200 yds with the 17/223. Super clear, I was impressed. The exposed turrets are a little mushy, but I won't need to dial much with this round at any reasonable calling range. I like the ability to use the hash marks to hold off for windage, however.
Going out calling in the morning with it again, will give an update if you're interested.
