    Has anyone actually used the Integrated Ballistic Computer with/without the included angle measurement? How well did it work with your rifle's dope?

    They have a new Leica 1600-B CRF out that is supposed to be available in June 2012.

    I would look into that one as well.

    I had yours and sold it to get a Vectronix. I never used that option on mine just used it for range and to get the angle. Im sure some guys out there have used it and I hope you get some responses.

    I have the current 1600 model and up until yesterday had not actually put the ABC (Advanced Ballistic Compensation) system to use. I was curious if someone had been using it. I posted the same ? over on Snipershide.com and 24hrcampfire.com and finally got a response. It was favorable.

    Leica 1600 LRF: actual use? - Sniper's Hide Forums

    So, yesterday am, I set up some steel to ring out a load in my 6.5x47 that I hope to both compete with in a 24hr Sniper Challenge and hunt with. The 130 Berger VLD running 2970 fps. Accuracy is running just sub MOA. Using a 6" round steel plate, I first set it up at 394 yds. I like the Evil Roy by Action Target for it's portability, ease of set up and ability to change out plate size.

    http://www.actiontarget.com/store/evilroyline/at-evil-roy-practice-target.html

    I used both the Leica 1600's features and a Kestrel 2500 for weather data. I also was comparing drops with the Shooter program on my DROID smart phone and EXBAL on an older Palm M105.

    First comparing weather.

    Kestrel gave 23.90 barometric station pressure in in/HG.
    Leica 1600 gave 11.8 psia

    You can compare the two here. It was a favorable comparison. The two readouts also were within 200' of my gps elevation.

    Air Pressure and Altitude above Sea Level

    Both units are temperature sensitive to radient heat (sunlight and body heat) and will have higher ambient temp readouts if left in the sun or held in the hand too long; especially the Kestrel. Temps were comparable in the mid 50's.

    It was nice of the Leica 1600 to give me 5 deg down angle. I used it's angle readout to input into both the Shooter and Exbal programs.

    Drops

    Exbal gave 5.25 MOA = hit
    Shooter gave 5.2 MOA = hit
    Leica 1600 have 4.7 MOA = miss

    I added one 1/4 MOA click up and hit the plate after the miss with the Leica 1600. For varmiting, it might behoove to add the click for hits but for general big game hunting, IMO, it would work quite well.

    I then moved the steel out to 450 yds, which was as far as I could before the terrain would not allow me to see the target.

    Again, weather readouts were similar.

    Exbal gave 6.5 MOA for two hits
    Leica gave 6 MOA for two misses but as soon as I added .5 MOA I was hitting again.

    It seemed that with "my" rifles dope, the further out I went, the more extra clicks were needed to hit.

    I plan on selling my Leica 1600 when my 1600-B arrives. I have it on order and will try and test it before the competition at the end of July. Knowing I need to ad a skootch to my drops does not matter to me. The time saved by not having to break out both the Kestrel 2500 weather station and either ballistic program could make a fast evolving shot happen.

    Any one want to buy a "LIGHTLY" used Leica 1600?:):D

    I thought it only figures curve to 500 yrds? Which is pretty much useless

    The new 1600-B coming out this month states the ABC will go out to 880 yds. A bit more helpful?.

    Is .5 MOA off a miss? I'm confused, but I'm new to this.

    The 1/2 MOA miss was at 450 yds. So, 4.5 x .5 = 2.25". Missed it by that much!:D

    Ok, technically it would be 2.25 x 1.047 = 2.36".

    Alan,

    Keep me in mind when you decide to unload the slightly used 1600...

    I was able to obtain my 1600-B in June and I absolutely love it. For the past few months I've been testing/using it, and it's one of the best tools a LRH can have with them. Something I've learned since my original report on this is my apples to apples drops are much closer if I use a 200 yd zero. Being a sniper competitor I always prefer a 100 yds zero. Out to 600 yds, I was always within 1-3 clicks. Problem was beyond 600, out to 875 yds, the max range available for the B model, I got further and further apart between the B model and my Shooter program for a max of 2.75 moa @ 875. Too much! Once I started using a 200 yd zero I was always with 3/4 moa. At 875 yds I'm only 1/4 moa off. Pretty darn great when one needs a firing solution, which uses range, station pressure, temp and up/down angle, NOW!

    The only thing Leica screwed up on when the took the original 1600 and brought out the B model was the read out for 1/4 moa drop is in "clicks" instead of MOA. This morning out my window I ranged some trees at 849 yds and got 85 clicks instead of 21.25 moa.

    Hi, new to all this. I have just bought a Leica 1600b solely for using the EHR function. However I don't seem to be able to set it in that mode. Unless it is in that mode and I don't know it. It never gives me an adjusted distance reading no matter how far or at what angle I try it. Do they give the actual measurement, then the adjusted one. Any help would be greatly appreciated. Thanks

    Dave,

    Sorry to say, I do not believe the 1600 has the EHR function. The 1600-B does. Even though I sold my 1600 a month back to fund the purchase of my new 1600-B, I still have the instructions in a PDF format on my computer. I just now read through them to insure I'm giving you correct info. I did not find any references to EHR. The good thing is, even though it may not give the corrected range, it will give you the corrected drop. Before buying my B model, I took the basic 1600 model up to the base of my local mountains which are about 1500 yds behind my house and range numerous distances up to 875 yds with angles up to 32 degrees and compared the drops with those on my DROIDS Shooter program. They were identical. So fear not, the device will give you the correct drops. Hopefully that is enough to get your what you need.

    Hi Alan, thanks for the reply. I have got the 1600 B model.. I'm just not sure how to turn the EHR mode on, or how to verify if it is on. Thanks again
