Reviews & Tests
"I have never had such reliable success picking up every single shot over a chronograph. Let alone rapid fire shots."
"MagnetoSpeed has provided one of the more elegant solutions for collecting shooting data.."
"MagnetoSpeed: A Chronograph That Fills A Need!"
"MagnetoSpeed: Next-Gen Chronograph"
"For the guy trying to test out his loads, it's perfect."
"I have no affiliation with Magnetospeed, I'm just a happy customer!"
Magnetospeed custom prototype testing @ Southwest Research Institute
MagnetoSpeed LLC worked with Southwest Research Institute
(SwRI) to quantify the ballistic accuracy of the MagnetoSpeed sensor package. SwRI uses a bench top range setup to do ballistic tests on ammunition and uses a double Oehler sky screen setup to accurately capture bullet velocity. In the table above, seven shots were taken all using the same ammunition (7.62x51mm M80) with the MagnetoSpeed sensor as well as the double skyscreen Oehler setup. Velocity 1 above is the velocity measured at the first set of skyscreens and Velocity 2 is read at the second set. When the muzzle velocity is back calculated based on the distance between skyscreen sets and the muzzle we obtain the "Calculated Muzzle" velocity in feet per second (fps). Comparing this to the Magnetospeed data we get percent differences of less than half a percent. This data series shows that the MagnetoSpeed is at least 99.6% accurate to the Oehler system used at SwRI for this test.
Magnetospeed Prototype: High-Speed Video Testing
The SwRI data was good but we wanted to know with more certainty how the MagnetoSpeed sensor stacked up against actual bullet velocity. In order to do this we had to see the bullet and calculate the velocity based on actual measurements. It was time to implement high speed video into our testing scenario. The picture to the left shows a slide of the high speed video we took and the home page shows a slow motion animation of a .243 caliber bullet exiting the barrel and crossing the sensor deck. Based on visual calculations and several test shots we were able to document a 99.9% average accuracy level with the MagnetoSpeed sensor with respect to the video evidence.
KMW- Long Range Solutions tests the MagnetoSpeed prototype
Terry Cross at KMW-Long Range Solutions
is an expert when it comes to building high precision rifles. We had him do some initial testing with the MagnetoSpeed Rifleman and one of his custom .308 rifles. He used Federal ammo and got a "100% read rate on every projectile". He said his next test will be to shoot the MagnetoSpeed sensor in tandem with a PACT chronograph using standard screens to see how the two compare. We are anxious to hear the results.
