Re: Chronograph suggestions....
Haven't had my magneto long but love it compared to getting an optical going. On the two guns I've used it on I have noticed very little if any change in how the loads shoot with it on. Never had it fail to pick up a shot and love having the data available on the SD card for later. I can't vouch for accuracy but I will say that my ballistics calcs are more consistent using the data attained with the magneto than I've gotten before.
