can some tell me whats all the hype with BDC scopes, just something about them I'm not sure about. something about the center of your cross hair not being on target is like shoot @ air. i feel if your going to shoot long range learn the formula and dial your scope 2 it. Anyways Have Great Weekend Everybody. I know I will Tomorrow My B-Day.

i think they are meant for "quick" shooting..... sometimes you don't have time to "dial-it-in"

Well there is a good side to balistic reticles and a bad side to them.  The majority of scopes that have them are second focal plane scopes which means that the reticle only accurately represents the known distances at the maximum power of the scope.  Zeiss has figured out that some cartridges are more accurately represented by a power slightly less than the maximum and their balistic calculator will explain how best to use their scope for your caliber.  One of the bigest problems wiht higher power scopes having balistic reticles is that as it grows dark you need to dial down the power to brighten the image.   6x42 is bright or 7x50 is bright or 8x56 is bright. Take a fixed 20x42 scope and look through it at sunset and it looks grey but that is not the fault of the scope it is just the physics of how much light is transmitted to your eye.  Leupold 6x42 FX3 with long range duplex is one of the few scopes that is always bright and the balistic reticle always represents the same distance.  Now we all know that different bullets in different calibers have a different trajectory so no one reticle is perfect for every caliber and one would need to test their scope at known distances to see how closely it matched the balistic reticle.  Lets say you had a 30-06 180gr Nosler Partition that you zeroed at 200 yds and had marks on the reticle that should in theory represent the 200 at the center of the crosshairs and next mark down in theory 300 and next mark down in theory 400 and next mark down in theory 500 yds.  However when you got to the range you shot it and found 300 was 3 inches high and 400 was 4 inches low and 500 was 7 inches low.  So long as you keep notes and I make notes inside the lens cap.  You can hunt an elk at 500 yds with that rifle knowing that the mark that represents 500 actually requires you to hold 7 inches over where you want to hit at that distance.  It is merely a point of refrence.  Also worth mention it the fact that both minute of angle and milradian are measurements of an angle which starts at your eye and the lines grow farther apart as they get further away.  So one can make up a balistic chart wiht the drop in 1/10 mil and use a mildot reticle for holdover just like a balistic reticle.
I hunt deer with a 50 cal musket that has a Nikon Omega wiht a balistic reticle. Large slow buletts have a really radical trajectory - like a rock so I find the balistic reticle quite handy since I usually set up my shots to be about 200 yds.
As for dialing in correction that is by far the most accurate method to correct for trajectory however tall tactical knobs are not ideal for hunting in the brush.  Leupold CDS custom dial system has made dialing in correction very easy as they custom engrave the knob   1 for 100yds  2 for 200 yds 3 for 300 yds  etc.  The really smart thing they did is make it a knob that could bemore hunting friendly.

I guess I am a bit different than most but if I'm hunting big game, I still rather have the plex sighted in 3.5 inches high at 100.  If the game is out of my range, it's too far and I need to be a better hunter and get closer.  If I'm at the range, I love a mil dot.  Small game, the mil dot or ballistic plex type of reticle is great.  All of that said, my latest scope is a Zeiss with the Z800 so I may change my mind on it all but right now I'll stick with what works for me.

My heartburn is with the guys who are out there shooting deer, elk or whatever at 500+ yards when they have no reason to be shooting past 200.  They have no idea what their bullet is doing once it's out the end of the barrel, let alone that far out.  I hate hearing stories about shooting at 500 yards becuase most of the time it's probably 250 to begin with and half the time they start talking about wounding the animal and needing many shots to finish it off if they even do finish it off.  I'll get off my soap box now, well not yet.  The TV show that takes Joe off the street corner and shows him shooting some deer at 800 yards just perpetuates this kind of action which is completely irresponsible in my view.

In my opinion these reticles are more of a marketing tool.  Sure they can be useful to some one willing to take the time to learn the functions, but I believe most people who buy these scopes just arbitrarily guess the range and use the next circle, dot or line that they think coincides with that range.

If used properly, BDCs can be great tool.  Makes for fast aiming, but you have to do your work and shoot with the scope at those ranges to make sure.  I like dialing it in, but some of my scopes don't have target knobs so adjusting dialing in would be a pain.  The BDCs in that case really help out.  As mentioned the downside is that they only work on one power, so if you have to use a lower power, the holdover won't work.

It's all just in what you become accustomed to and are willing to make the time commitment to learn  the BDC's and where the points of inpact are in relation to the reticle...It can be time intensive, but worth it in those situations where a long range shot may be needed ..
