Fishman,
You have what it takes to shoot long range. #1 most important thing is to know your limitations, which you seem to know.
My cousin's little boy killed a nice 8 point last year with a Savage .243 at 276 yards from a stand...those yards was ranged with a Nikon rangefinder...Practice makes Better.
He uses the Kentucky Post System :lol:
With a standard duplex reticle you have crosshairs sitting on top of a thick post...well that thick post is not zeroed at 100 yards, the crosshair is...so learn to use the top of that big post...
An effective way to judge distance is to get a full size deer decoy/archery target and sit it up 200 and 300 yards away and see what power setting the deer "fills" up the crosshair part of the reticle(between the big posts)(make sure to judge from chest to rump), that way you know if it fills it up on 7x it is 200 yards and if it fills it up on 9x it is 285 yards(just examples, every reticle size varies)
You also have the bottom of the post, and also the middle of the post but stick to just the top of the post to begin with, don't rush yourself.
The more you practice at longer ranges the easier it is to judge distance...
you will know, in the back of your head what distance it is...example : "That buck is about at my top post distance."
Practice makes Better.
I am not sold on the whole Leupold thing...I prefer the Nikon Monarch myself.
The single most important thing to worry about is WIND, which the B & C Reticle does not compensate for anyway...
I would hate for you to wound a deer because you had trust in a "ranging" reticle.
Oh Yeah, when practicing and judging distance always use the same magnification setting as well as your naked eye...distance looks different through 5x than it does through 7x...with the exception of the "chest to rump" method I mentioned above.
Practice, Practice, Practice. :grin:
