Medium or fine duplex on new scope?

I'm thinking of buying a leupold 3-9-40 and it comes with the medium duplex.I saw on premier reticles where you can get one with the fine duplex for about 20 more bucks.My question is,will the fine duplex be much harder to see in low light as opposed to the medium.Also,would the 4-12AO be a better choice on a 17hmr because of the AO since most of the shots I take are within 100yds.I've never owned a scope with an AO and I'm not really sure what it does for you.I think it allows you to focus the scope at different ranges,is this true.Sorry about so many questions but I figured you guys could put me on the right track.

AO's

stiffwindpsr,
I've never owned a scope with an AO and I'm not really sure what it does for you. I think it allows you to focus the scope at different ranges, is this true?
Regarding AO's [Adjustable Objectives], read my Post entitled "Focus" in the thread entitled "parallax adjustment" in this Forum.

Also read "Sticky: Setting-Up a New Scope" at the top of this Forum. It discusses using an AO scope for hunting.

My question is, will the fine duplex be much harder to see in low light as opposed to the medium.
The 'fine duplex' is for target shooting under bright light conditions. You will lose it in dim light conditions, especially if in brush or grassy areas....! ! :(

Power of a scope is driven by the size [detail] of the target, and not the range. You can hunt elk with a 4X scope at 500 yards; you would be hard pressed to even 'see' a PD at that distance with a 4X....! ! :eek:

Hope this helps....! ! :)

I use a 4-12 AO Leupold on my ULA for squirrel hunting. The fine duplex is not really a problem for me, the squirrels in this area usually quit moving before the reticle fades (read owls). I have it set at 6X most of the time, but do go to 8X or 10X for long shots (using a rest) occasionally.

I especially like the 4-12 AO for target work, nice to have the 12X. It's almost the same size as the standard 3-9 Leupie, so you're not dealing with a huge scope. I believe it's the lightest of the 4-12's also.

You won't be disatisfied with either scope, if you get the 3-9 Premier will set the parallax at your required range (80% of maximum distance) for free. Leupold charges $15.00 plus $7.00 return postage. Dick Thomas of Premier has some competitive prices, IMO.
I prefer the med/standard duplex for field use and hunting...the fine version sometimes gets lost in the branchs and weeds while hunting for me.....I think you will enjoy the added power of the 4-12 and the AO is needed on a accurate gun and I've heard the 17 is doing well for accuracy...the AO can be preset for the general distance you will see durring the hunting shooting and be used without resetting most all the time......and when you want the final little bit of accuracy and clarity at the target you can fine tune the AO and after a little while you do it without thinking and part of the routine.......good luck and good shooting!!
Thanks for the info guys.That clears everything up for me.I'll probably end up flipping a coin or going with the 3x9 and saving 100bucks.
