When pursuing accuracy...

1. How useful is a chronograph in general?

2. Any thoughts or opinions on specifically the Magnetospeed product?

I used to be a stickler for chronographing during load development, and used an optical. Then realized, when I gwt one shooting tight, it tended to also have a low ES. I never cared how fast it went, as long as it was consistent.

As far as the Magnetospeed, they give dang accurate numbers, but I don't want anything touching my barrel, especially during load development. "They" say all it does is shift POI, but I don't buy it. Its got to change harmonics. If that was the chronograph I had, I would develop a load without it, find the winner, and chrono after the fact.

^^+1. Would love to have a good chrono but consistent velocity is much more important. Once you have a load you like you can use ballistic app(s) to calculate your velocity. P_102

I moved to a Magnetospeed from optical this year. I only use at the end of load development to gather data of final product not during for all the reasons stated above.

Pretty dang nice to have a Magnetospeed to assess which factory ammo is the most consistent, and have a solid MV to plug in a ballistics calculator. Saves a lot of time and money coming up with a dope chart the ole fashioned way. Once all that is accomplished, it gets put away until there’s a new situation to assess.

I love mine. Like others, I use it after I find a good load to know the velocity.

I would be blind without a chronograph. I chrono almost every shot I shoot on the range. I use a Lab Radar. Used it again today.

The main thing I need to know is where my velocities are in relation to the powder and powder charge I am running. And where my accuracy node should be with the speeds. I seriously would be loading ammo blind without it. It's a necessary tool for me.

I'm a control system / instrumentation specialist and can't see how something like that so close to the barrel can take that kind of repetitive abuse and be consistent.

I didn't say they couldn't just amazed how they can keep measuring with enough accuracy to get you in the ballpark to build a range chart to get you on paper down range.
