I have used both and they both have their place. For big game I pretty much prefer the dialing method with a turret. The B&C reticle only has hash marks to 500yds also, although on mine the flat bar at the bottom worked for my 160gr 7 mag load at 600.
The advantage of the reticle is it's faster and there is no turret to get accidentally turned. I like it when shooting coyotes at a distance, because they don't often stay in one place long enough to range and dial. I can range the coyote, follow it in my scope, and be ready to shoot the next time it stops. If it moves a lot I estimate the change in range from where I measured it. Disadvantage is having to"bracket" animals at intermediate distances (say 450 or 475yds) makes it harder for me to pick a precise aiming point. It works but takes more concentration for me than dialing and putting the crosshair dead-on. My favorite scope of this type is the Leupold VX3 with the Varmint Hunter reticle. I like the finer reticle than the B&C that doesn't cover as much of the animal at distance.
The turret's advantage is precision. With a properly matched turret you just dial the exact range and shoot. I like a reticle even in a turret scope that has MOA hash marks on the horizontal crosshair for wind adjustments. I bought a Swarovski Z5 with the 4W reticle for my 264WM that I really like after last hunting season and moved my Vortex Viper with the MOA reticle to my 6mm. I still have a Leupold 4.5-14 on my 270 I take in the mountains, it has the VH reticle and I had the CDS added to it.
Best piece of advice I can give with either method is to get a really good rangefinder that calculates angles. Neither system works if you don't know your range. I broke down and replaced my Leupold 1000yd rangefinder with a Leica 10x42HD-B binos with the rangefinder built in. I can range animals much farther and faster now, the extra bulk and optics of the binos makes it so much easier to hold steady. The leupold reticle was almost impossible to see in low light, this one is not. Best hunting money I have ever spent.
