    Measuring BC - Oehler '89

    The BC is calculated from: Air density (from atmospherics you input - including wind), velocity - measured, TOF - measured and distance (from your input).

    Measuring BC - Oehler '89

    The variables are in the settings. You input atmospherics, screen spacing and distance to target. After shooting you can change those variables and replay the test. I'll send you my email address in a PM.

    Measuring BC - Oehler '89

    One of the best things about this system is the ability to shoot once and analyze variables later. Shoot the test once then change whatever variable you are interested in and replay the test.

    Measuring BC - Oehler '89

    Good to hear. I'm looking forward to the things that will be learned as this capability is picked up by more shooters. We would all like to have a radar capable of tracking bullets deep into subsonic. This is the next best thing. I've used it side by side with long range radar and they gave...

    Measuring BC - Oehler '89

    I heard an Oehler '89 was at the KO1M match and that people shot over it to get data to use. If anyone knows, did the data match up with shooting the match? I know my experience has been the data is spot on but it would be interesting to know the experiences of others. At White_Shark, sorry...

    Measuring BC - Oehler '89

    Whatsupdoc said: Dont know how accurate the results are it depends on how accurate the Labradar numbers are. The LabRadar machines have shown to be capable of giving very good numbers. If I run two and get the same (or very close) numbers, I trust them. I've had issues with muzzle blast or...

    Measuring BC - Oehler '89

    We all chase a high BC, and why wouldn't we? One of the most important things most overlook is the consistency of the BC. Long ago, I thought BC was a static number. I got it from the manufacturer and it was what it was. The same number was appropriate for everyone, for every shot. Modern...

    Measuring BC - Oehler '89

    One other thing to think about is that if someone else tests them you will only know what they do in THAT person's rifle. They may not show the same performance in YOUR rifle(s). Think of it like you would think of asking someone to shoot your loads for velocity. You would be far better off...

    I'd also like to add that there are a few '89s out there already. If one of the users reads this, he may be willing to test BC just for the opportunity to see your bullets and get more familiar with the system.

    Measuring BC - Oehler '89

    Depending on how many you wanted tested and the time it would take to create loads then actually do the testing, it would likely cost more than purchasing an '89 so you could test them yourself. I'd be happy to discuss with you and offer some recommendations. I'll try sending you contact info...

    Measuring BC - Oehler '89

    Having seen recent information on the Oehler System ’89, I thought I’d get a bit more out there for those that may have interest. Disclaimer: I don’t work for Oehler Research. I’m good friends with Dr. Oehler and have used his equipment for many years. Any work I’ve done with Oehler Research...

    Oehler - BC ChronoTM System: System 89 Ballistic Coefficient Chronograph

    Oehler Research started shipping the System '89 last month. I've got thousands of rounds on one and run it simultaneously with Doppler radar. It gave the same BC number. I've used it at distances from 100 yards to 2 miles. It will measure velocity and TOF and calculate BC for you. It will...

    Re: Online Copy of FBI 308 Ballistic Tests Thru Glass? Actually, it is one-stop-shopping. You don't need to be caliber specific in your request. If you ask for any data, you'll get the CD. The CD contains all data we will release.

    Oehler 35P Thoughts & Review

    Re: Oehler 35P Thoughts & Review Chronograph numbers don't sound right? First thing to check is the spacing of your screens. I believe the CED system operates on a 2' spacing. I believe it also has a mounting bracket that folds. If you are using it on a tripod, the arms can overextend...
