How accurate are the CDS scope turrets by Leupold? Anyone had any experience with them?
They are as accurate as the information that you send them.
The reason I ask is that I am in search of a system that will allow me to (in brief terms) Range, Dial, Shoot in a hunting situation.
Would I be better served sending Leupold my numbers and having them make custom turrets?
Having them put, say, an M1 turret on the scope - developing a chart, tape it to the gun stock, and..... Range, Reference, Dial, Shoot?
I have a CDS system on a semi-custom 7mm mag with a 200 yrd. zero. It's dead on out to 800 yrds. The possitive stop won't let it go farther. But for the money it's well worth it. Just my two cents.
Like i said before, as long as you send them correct info, they will be awesome for a certain elevation, and a certain weather condition with a certain load. I may get a set in the future, but i am pretty comfortable just having a drop chart for the current conditions and just using MOA marks. Think i would have them made for the average conditions and altitude that i am going to shoot at the most.
This was one of the issues that had me on the fence about them. They are only good for those EXACT conditions they are "programmed" for
(even though they will still be BALLPARK).
Could the CDS turrets be swapped out to accomodate other conditions, extreme elevation changes, etc. relatively easily? Not saying I would want to carry 3 sets of turrets with me while hunting - but if I hunt with one set here in Appalachian Region the majority of the time and then decide to go on a trip out west simply switch out the turrets and be good to go.
If you have a good ballistic program, you should try entering different variables into the equation (such as change in elevation, temp. etc.). I think you will find that there is no change in your drop chart for the first 600 yards, regardless the conditions. Out to 800 yards you may find .25 to .50 MOA click difference, but nothing that you couldn't adjust for. At least - that is what I found with my specific load and rifle. Your mileage may vary.
They are swappable, and your really shouldn't have to carry two or three sets with you like the above poster said, if it is just the difference between target shooting in the summer months and hunting in the winter months, that can easily be compensated for with minor adjustments. If i where to do it, i would have one made for my home hunting spot and one made for a drastic change in elevation for the mountains out west. For my self i'm at around 1000ft, when i go to the mountains, i more in the 8000 range
if you get regular turrets, do they also only turn one revolution?
Your turrets should turn until it tops, or bottoms out. I think the one turn thing was just the markings on the turrets are made for one complete turn. After that the custom part goes out the window. You will have to know your drop and count MOA's after that
The CDS turrets have stops on them at your zero and at 1 revolution of the dial. Like somebody said above, you get 15 MOA in one revolution. Plug all of your info including your zero in a ballistic calculator and you will find out with a little simple math what kind of range you will get for your caliber/bullet/load..... I just got mine in the mail yesterday and installed one on my scope so I know they stop at zero (200 yards for me) and after one revolution (about 700 yards for my 300 wsm and 750 for my 340 wby). I ordered the two free dials for two different guns/loads but still need to send in the vx3 on the wby to get set up for the dial ($90 since I already have the dial). Will be sending that one off next month.
I am overly excited to go try this system out. I had the day off today but it rained all day so I didnt get to go shoot. Will be testing the 300 wsm out to at least 600 yards on Sunday.....
Let me know how they work for you. I am really leaning towards putting on on my 300win mag with a 20MOA base
If you by a cds scope of the shelf the dial has no stops. If you order dials from the custom shop they have stops limiting you to on full turn.(one full turn is roughly 750 yards in a 270 WSM)
I dont like the custon turrets you change alt or load or what ever they are wrong. I would go with a standard MOA turret and use some sort of ballistic software to print out drop charts for your shooting needs Alt,load ect.
I did this for my buddy with the 270WSM. He use his home chart a got a nice buck at 750 yards and the we printed a new chart for a Wyoming elk he was dead on at 6000 ft drop his elk DRT.
I like this system so much I have 4 scopes in the custon shop right now Two getting cds turrets, one m1 turrets and the other a mill dot reticle
You can order the turrets from the custom shop without stops, and an additional row of numbers, so you can get more than one turn. I had them make one for me, and it works great. I also had a custom one made for around here when its chilly (35 F, 7000 ft). The standard factory CDS turret is on the left:
