Magnetospeed and Harmonics

[RockyMtnMT]

I'll develop loads with the Magnetospeed on the barrel, I've seen a few move the POI but I have not see a change in groups size with the Magnetospeed. I'd rather risk the magneto causing an issue than to do total load development without solid velocity data.

I also use it this way. This way I have an idea of pressure as velocity climbs. Once desired vel is acquired then the magneto comes off and seating depth tuning takes place.
