Magneto Speed Question

[17remhunter]

Right now im using a Magneto Speed Chronograph. Can using this chronograph affect my barrel harmonics and have an affect on my group sizes when working up a load

 

[Nicoli7153]

Absolutely! Use it to get your velocities and other data (ES, SD) dialed in and then sight in without it

Yes, from what I've seen it definitely does effect my group size. Not a ton, but 0.5 MOA or so over 10 shots

Yes it can, I’m an avid hand loader and I consider a reliable chronograph a necessity. Last year, I bought a Garmin XERO. The Garmin has been the best addition to my range gear in years!

I've had this issue as well what I've notice was a .25" shift with the speed on
