Howa mini action factory load test- results

[Matt @ LSI]

Matt, have you found any differentiation of group sizes when the Magneto-thing is or is not on the barrel? Just curious.

yes, and i tested this with 2 loads and had the same results.
with magnetospeed on, POI shifted 2 tenths low and 2 tenths left, group size was a bit erratic.
I expected this, my gas Grendel has the same effect.

Thank you, good data. I've noticed more POI shift ( 0.5 to 1 MoA) and variability with a Magnetospeed on my 24" std bbl.
