Rifle Chronographs

[Doug Brownlee]

I am looking for a new Chronograph the one I had was expensive and with in the first year I had to replace two light elements not covered by warranty (electrical) any ideas.lightbulb

The cheap ones are wrong most the time, the expensive ones are still wrong some of time, and there is no way of knowing when it's good and when it is full of crap. Gravity:cons: not fancy,it has no printer or led display....... Gravity pro: It does not require a tri-pod, , It fits neatly anywhere and everywhere and it never lies, misleads or fails, you can not accidently shoot it and it's cheap, works in any light....etc,etc..........Drop test results reverse engineered threw a good ballistic calculator is better info, more reliable info. Making the chronograph the #1 contestant for the most over rated piece of gear on the planet and a total waist of money. My opinion and I am sure others feel differently but it is what it is.

Don't waste your time and money with the light sensor types. The area detectable is limited and they can be a real pain to get accurate readings from in poor light conditions. What you need is an accoustic chronograph. These record the shockwave created by the bullet as it travels across it and have a much greater detectable area -.
Here's the one i have:

The World

I particularly like its compact size and the fact that i can set it up near the target without fear of false readings. Thereby i can confirm bullet speeds out to extended ranges and compare against ballistic calculators.

Here's a U-tube of it in use:

Have used two different brands of light sensor types. Both worked but would be finicky depending on the brightness and angle of the light. And I shoot at a range so is always a pain to call a cold range so go play with mt tripod

I switched to a magnetic sensor type that attaches to the front of my rifle, works in any type of light. This is by far the best I have used. The one I have is called a Magnetospeed.

I'm having good luck with the magnetospeed. No tripods (still have one of these) no light diffusers (it'll even work in the dark) & has not effected accuracy (only POI).

MagnetoSpeed


Not super expensive, doesn't weigh anything & doesn't take up much space (I keep mine in my range bag at all times).

Thank you for the feedback, you have broadened my horizons. I looked up both units and for ease of simplicity I am going with the Magnetospeed unit. I will post the results of my 300wsm and 270.

 

[Outlaw6.0]

Welcome, glad to help. Keep in mind, your POI will shift slightly with the Magneto Speed but it has not effected accuracy as far as group size goes. That will allow you to work your loads efficiently, but you will have to remove the unit to zero.



cheers,

 

[Doug Brownlee]

thanks for the POI info. I always cold bore zero. My 300wsw hits a postage stamp at 200yds. I will have to see what the 270 will bring. I first have to learn the trigger pull on the 270. My 300 is set for 3lbs while the 270 is 5.3lbs big difference.

Will the magnetospeed chronograph work with bullets of non-megnetic metals such as the copper Barnes types?

 

[Doug Brownlee]

the directions say there are different settings for the different alloy bullets.

 

[Outlaw6.0]

Will the magnetospeed chronograph work with bullets of non-megnetic metals such as the copper Barnes types?

Yes, i've used it with both the Cutting Edge Bullets out of my 6.5 WSM & Barnes out of a 300Win, both worked just fine. I did not have to use a different setting but they are there just in case.

Is there a place to look at this thing in American speak and dollars?
