The editor finds a truly portable chronograph for the masses
The editor tries out the Ballistically Brilliant Chronograph from the Shooting Party - compact, and so easy to use
As I hope you all know, we live in a country in which the maximum amount of power our airguns make is restricted by law and that is our duty to ensure that our guns never exceed this. For rifles, the limit is 12 ft.lbs. and for pistols 6 ft.lbs and the ONLY way to check it is with a chronograph that measures the speed of the pellet as it leaves the muzzle. This figure, calculated with the pellet’s weight, tells us the vital information we need, and because of this I’m happy to see The Shooting Party offering their ‘ Ballistically Brilliant Chronograph’ (BBC). Apart from being very clever, it’s available at a pretty modest price, so more airgunners will find themselves able to own one.
One of its best features is that it’s fully self- contained, running on an in-built rechargable battery, so you can do your testing anywhere you like without the need to be near mains power. It’s truly tiny at just 4” long, and weighs next to nothing, so could be carried to the shooting range with ease. I also like the fact that it has its own light sources for the sensors, rather than ‘sky screens’ that can be annoyingly affected by changing weather conditions.
I ran a side-by-side test with my expensive, professional quality chronograph and it agreed with the BBC within the advertised <+1.3%, reading just slightly higher on average. It can record your strings of fire and also stores the time of day, the rate of fire, plus the temperature and humidity at that moment. The latter data will be very useful for later comparison, especially on temperature sensitive guns like CO2 models, when even a few degrees of difference in the ambient temperature can make a big difference. Those who really like to analyse and store their test results can download the data to computer with the cable supplied via a free software application.
As it’s so easy to transport, I was glad to see that the housing is all-metal, so I expect that it could survive a knock or two without breaking. Great caution is needed when shooting through any chrono’ and with the aperture here at just 32 x 37mm, you’d better be sure you’re correctly aligned before you pull the trigger. That being said, I had no problems at all and got a good reading from every shot.
The BBC is a great little tool that will make power- checking guns easy, and it’s available to so many more people than before. I know the first batch sold out, and lots more will be arriving as you read this, so you won’t be disappointed when you go to find one.
