I’ve been using a MagnetoSpeed V3 barrel mounted ballistic chronograph a few times a week for the past few years (I started with the V1 back on December 2013)! Thousands and thousands of reliably measured rounds later, my unit is BROKEN!
Take a look at this data set:
That’s right, one round at 204 feet/second, the next at 2,752 feet/second, and the last at 7,530 feet/second! My loads aren’t that bad! I tried to fix it with a few different batteries and checking the set up, after 50 rounds I gave up.
No, it isn’t the battery or the set up. It just stopped working. I’ll tell you what; for the thousands of rounds that I have fired through scores of rifles with this unit, it has done a great job. I’ll be ordering a replacement shortly.
It’s been real. This chronograph has been more than a chronograph to me! This is the unit I’ve used in countless reviews, load development, and barrel length posts. It is the same one I put up against the Oehler 35P here.
Here are some pics in tribute to its years of hard service!
