Hi all, I am looking at the Nikon M-308 that will soon be coming out and would like to hear opinions between the 800 yard BDC reticle or the dial your range turrets which I think this scope is going to have. It will be mounted on a .308 so most hunting shots would probably be less than 400 yards due to bullet energy but would like to make some 800 yard target shots in the future.
I have been watching some of the long range hunting shows but can't afford the $3000 scopes those guys are using and it seems like they are all using the dial your range turrets.
Thanks for your thoughts in advance.

Here is my thoughts, BDC reticles are generic, chances that yours matches what they calibrated it to are slim. that said, time at the range can get you enough knowledge that you can use them accurately but they won't take that away. Also they are different on different powers, so if you check it on max power but have to turn down the power in low light your drops are off.  Keep that in mind.

With turrets you simply dial in your shots no matter what power or distance.  You make yourself a chart and tape it to your gun, no mater what power your on your crosshairs will be on target and you'll have dialed into the right distance.  This also take time at the range and in general is much more precise than using BDC reticles.

IMO, learning/being able to shoot a .308 out @ 800 makes it worthwhile to learn how to use a ballistics calculator, establish real-world drop tables and use a reticle with uniform subtensions (either mil or MOA) with matching target turrets. If you're going to go over 10X on the high end, seriously consider going with an FFP scope. Then you can make corrections with the reticle at any power.

I noticed on Nightforce scopes that are dial in turrets that you have to get several different turrets for elevation/temp changes which makes sense. Nikon is advertising their custon turrets for $99 which adds quite a bit if you are wanting a gun for different environmental conditions.   I would think with the BDC reticles, you just have to carry the ballistic tables with you that would show the difference in your mil dots for the environmental conditions.  Am I understanding this right or is there more to it than meets the eye?

the trick is knowing the correct distance, the rest is just physics. If your using a lrf , then neither method has an advantage over the other. If your using hold over, either in the reticle or dial in the chances are the target is out there, simply because you are using the hold over, and fov isn't a priority, so you will be using the scope on max. power in all probablilty. (if this is a problem in the area you hunt use a lower range variable). the most accurate method from the scopes point of view is using a combination of both hold over and dial in. the most accurate method from the bullets point of view is knowing velocity, bc, station conditions. the most accurate method from the shooters point of view is getting closer so he doesn't have to lay down in the snow.
