Magnetospeed while shooting a ladder?

[jasent]

I know on my sporter barrel it definitely affects poi but on my straight tapper remage barrel no poi change Out to 735 yards so far

I wouldn't do it. I had poi change and group change sizes. I purchased the labradar and everything is all good.

I own both the Magnetospeed and the Lab Radar. I have been able to use either to achieve comparable results. The MS does effect my POI which requires doubling up on my test loads for measuring POI and velocity testing independently. More often then not I find myself using the MS which, IMO, is very concise, easy to set up, and uneffected by other shooters in close vicinity. This is a recent check on new lots of Berger 130 Hybrids and H4350 used in my 6.5x47 PRS rifle, checked with my MS. Total, 10 rounds in duplicate for the ladder(with a bit of wind) that I used 5 for velocity, 5 for POI, and, 5 rounds(for group) at my standard charge weight of 41.2gr. New lots were consistent with the prior lots .
