Magnetospeed has just introduced a new bayonet-style chronograph that is less than half the price of previous MagnetoSpeed models. This is big news for shooters who always wanted a MagnetoSpeed but found the $399.00 cost (for V3 model) too pricey. The new Sporter Chronograph will cost just $189.00. It offers most of the features of the more expensive models (see chart below for details) and has a updated sensor. The MagnetoSpeed Sporter chronograph kit was designed to be used on barrels from 1/2 inch up to 1 inch in diameter. In can also accommodate muzzle brakes and flash hiders up to 2.7 inches in length. MagnetoSpeed says its new Sporter is “Ideal for contoured rifle barrels (sporter barrels) and long-barreled revolvers.”

MagnetoSpeed Sporter features

• Simple, one-button cycling display (shows recent shot velocity and statistics).
• Three sensitivity settings for fine-tuning.
• Easy access battery compartment, with 9V Battery included.
• Integral, quick-attachment system, with metal buckle, nylon strap, screw-in tensioner, and dual V-block spacers (thick and thin).
• Bayonet works with Muzzle Brakes and Flash-hiders up to 2.7″ long.

Q: Will the Sporter Chrono work with thicker barrel (i.e. greater than 1″ diameter)?

A: The manufacturer recommends the $399.00 V3 model for thicker barrels. But, wink-wink, if you have a 1.25″ barrel you can get this to work, based on what we’ve seen. If you need to go really fat (up to 2.0″ diameter), get the V3. Magnetospeed also says the V3 is needed for airguns, shotguns, and muzzleloaders.

This photo was taken by Jay at the Cascade Shooting Facility in Ravensdale, WA. The rifle is Jay’s .284 Shehane F-Class rifle. Jay was testing primers for Extreme Spread (ES) variation around 9:00 am. Nature was not cooperating. Jay was running Hodgdon H4831sc and testing various primers to see which provided the best numbers.

The chronograph is the Kurzzheit PVM-21. Equipped with infrared sensors, the PVM-21 is our “go-to” chron for most velocity testing, with an Oehler 35P for “back-up”. The PVM-21 (now updated with Kurzzheit’s BMC-19 model) sets up quickly and gives reliable results in any light conditions. But there is something even more sophisticated on the horizon — the new Labradar, a “stand-off” chronograph that uses Doppler radar to measure bullet speed.

Jay explains: “I am (somewhat) patiently waiting for the new Labradar to release. The PVM-21 works pretty well most of the time and is easy to setup. I do get odd readings out of it every so often, but they are pretty obvious when they occur.” The advantage of the Labradar (if it ever comes to market) is that the unit sits to the left or right of the rifle. The Labradar is situated out of the bullet path, so there is no chance of shooting the chronograph by accident. Another advantage of the Labradar is that you can set it up without needing to go forward of the firing line, which would require a safety break.
