Leupold CDS system


I have been shooting the CDS system for at least 3 months now. I want to hear others opinions on your own experience with the CDS system. I am old school shooter but now with this new technology you can really clear some of the guess work out of the way. Well I zeroed my scope in at a 100 yards and put the turret on. Next I turned it to 200 yards. I shot two bullets with in a 1/2 inch. Next moved it to 300 yards. 3 inches to the right of center and a high about 3 inch. Probably my fought. Well the real test. Shot out to 600 yards just high over the cow patty. Shot two more times and put 1 round just low to the left and the other to the right. I have never shot out to that distance before. But feeling more confidence in the CDS system but still not a 100% sure of it yet, still new to me. The one other thing I am not crazy about is the windplex, just to much junk in the scope. Some times hard to see your cross hairs on the target. So what are your pro's and con's about the CDS system by Leupold Scopes.

Here is my gripe with its premise.
It assumes a constant drop. Well what happens when your favorite ammo changes a component, or redesigns a bullet, or you change bullets, or you shoot in radically different weather? All perfectly normal and regular occurrence, that renders your dialing system off. If it is a SFP scope, you can't calculate distance to verify how far your shot is off.

Pappy1,

I like my CDS (Custom Dial System) scope which I have mounted on my RUGER #1 45/70.

Considering that anyone buying or using this scope should be perceptive enough to know/understand that the correct dial markings and setting during use require that the owner supplies data as per bullet weight, B.C., velocity, elevation, temp. etc. etc. etc. when ordering their "Custom Dial". I can not see the comments of the settings being off when the ammo is changed as being very valid. SORRY Darkker, sure no offense meant or implied your direction!

Of course they are. How could I expect the dial for my 465gr Wide Flat Nose 45/70 load at 1650fps to work if I changed the scope to my RUGER Hawkeye 300win mag with a 165gr Nosler Partition at 3318fps! OR even if I want back to my first 355gr Wide Flat Nose 45/70 cast hunting bullet, WHICH I WON'T, at a velocity of 2300 - 2500fps.

BUT THEN, I am for the most part a one load/bullet for one rifle person, seeking to find an optimum load and bullet for a given cartridge/rifle, and developing this load with the idea that it will be used for all game for which that rifle/cartridge/load may be used.

Therefor, I am not changing loads or bullets.

However were I to do so, I would expect to contact Leupold and order a new "Custom Dial" for that new bullet and load or rifle.

My 2016 elk was taken at 161yds and I had set the dial at 150yds, expecting that to be about where the elk would come out from the bottom where I first saw them.

One shot, one dead elk. 465gr WFN at 1650fps

I like the Leupold CDS scope and to this point it is doing just fine on my 45/70.

I have been thinking about buying one for the new 270 I am receiving in a trade. It almost seems heresy to buy a scope that's not in mils, and that I cant basically adjust for any loading. But, once I find a load, (I am hoping a Accubond for elk and deer) I wont change that load ever, and it will take a lot of the fumbling around in the field when I see a buck or bull at 400-500 yds. Simple twist the dial and your done. Leupold is good glass too!

I'm going to have to read up on the CDS system. I'm the ytpe that likes to find one bullet, one load and keep it simple and consistent with a particular rifle. It sounds as though for the person who doesn't like change, the CDS system will work well.

I make no claim that they don't ever work, but as I said and was danced around by others; when do things ever stay the same?
It has nothing to do with mils or moa being better, it had to do with flexibility.

No one here ever bought a bullet that got discontinued or suspended, especially recently by a certain company??
No one here ever struggled to find their favorite powder, never had to do an alternative?
No one here ever bought more factory ammo from a different lot, that wasn't the same components?
No one ever hunts in different temps or altitudes?

So as was pointed out, you can buy another wheel as needed; Brilliant! Except that means something changed as I asked above. So you spend something, let's say a week because a hunt is coming up. A week lost looking for some out of stock component. Then you have a few days or week to ship in the replacement. Then you have a few days or a week working a load that will do what you want. Then order your wheel and wait a week or more. Now you better pray the weather is what you thought for the hunt or the wheel is off again. That is an awful lot of time spent, added to your regular life and responsibilities; not to mention an awful lot spent on wheels...

Buy a FFP scope with matching turrets and reticles. If inches keep you safe at night, buy the moa version and you are set. Point is you buy your scope, and don't continually keep spending money and time waiting on hamster wheels to keep you close to the shot. For the price of one set of hamster wheels, you can get a quite nice Android or other device with your favorite ballistics app.
Then you have drops at your fingertips during the hunt. You can get to where you are going and verify velocity and zero, can't do that and have drops correct with the wheel of things have changed significantly.

By all means if the wheels make you happy, you should do it regardless of anyone else's thinking. But as we were asked for opinions, I just don't see any value but rather a lot of money and time.

I understand the appeal of the CDS. You don't have to remember or write down how many clicks it is to change from 100 yard to 200 yard zero. For big game hunters, particularly ones who 'never change anything,' I don't see or understand the value, but appeal and value are often not related, I find.

Here's what goes through my mind when I consider the value of a CDS type of idea:
What's the larger source of error: Being off 1 or 2 clicks at 300 yards vs where I meant to be, or being off in my range estimate by 25 yards at ~300? Anyone with any field experience knows that a miss due to incorrect range estimation is many times as likely as a miss because you were off by 1-2 clicks. If you carry a laser rangefinder, that's great, but if that's the case I doubt it's beyond your capacity to stick a drop table to your rifle or sleeve or somewhere.

I'm sure the CDS is really great for those who want and like them. Again, I just see no value, desire notwithstanding.

You are of course 100% right darkker. Nothing stays the same and everything affects the outcome. My comment was primarily in jest.

That said, the first turret is free from leupold, so why not. If you want to use someone elses custom turret, such as kenton, they recommend you get a scope with cds for compatibility (I called and asked before i ordered my scope).

If you view them as a sanity check, they are nice. But just like a bdc reticle, they are a quick reference.

The first turret is not "free." It costs $65, which is the price difference between any given scope in their line vs. the CDS option on the identical scope.

Call it what you want, but for the 45/70 it is a HUGE step up from Kentucky wind age!

I'm not a big fan of the BDC reticles, I own several, and they work ok. Most dedicated hunting scopes that I have are adjustable in 1/10th mil with exposed turrets. For longer shots, I Range, often with the reticle, and dial my appropriate hold. With the cds system, it won't be much different, other than I will Range with a range finder, and dial the shot. It's the same concept, only I feel more precise than a BDC reticle since your dialing actual distance. So IMO there's not much advantage of one system over the other.

I would have to agree. I have grown to feel more comfortable dialing. I do like the ability to adjust the bdc reticle to whatever ammo i am using on my sfp scopes (instead of changing dials). Its never in perfect even increments, but close enough. The downside is it introduces another source of potential error. Instead of the possibility of dialing incorrectly, there is the possibilty of moving or setting the power incorrectly.

Darkker I do agree with you on the weather and the other environmental elements. This all comes in to the affect of the bullet point of impact. It really does not matter if you have the CDS system or not. This will effect all guns and scopes. Just to much to worry about. Like I said, I am not a 100% on the CDS system yet. There are just to many variables while out in the hunting field. Like a quick shot at 400 yards, you might not have time to dial up your scope at 400 yards. But there are also a lot of positives about the CDS system. Like a good friend of mine said, you come across that Trophy buck at 500 or 600 yards and now you have a very good chance of making a kill instead of using Kentucky windage. I think most hunters that hunt can agree on most shots are less that 300 yards. I have only made two shots over 400 yards. Like I said, great technology out there but sometimes its just hard to change. I really like that video on Lepould web sight, the guy shooting the AR 15, Neat system with the CDS, I just wonder how long it took them to fine tune that gun and scope before they got it dialed in.
