First "zero" spread group...

In a way, but kinda not...

If I put that target into OnTarget, and assume the triangles are 1 inch to the side, and are pretty conservative about where I put the 3 rounds (make the groups possibly larger than they really are, but it's hard to tell, especially the bottom target)...

Then the conclusion is that magnetospeed expands the group size from .185 (lower) MOA to .220 MOA (upper), for a 15% reduction.

If I were shooting 1.5" groups at 100 yards, a 15% reduction after strapping magneto on would be 1.75".

So it does kinda go to hell

funny. I re-tried, this time only putting bullet holes where I am 100% a hole is, since there is no paper. Best group is .150 MOA, really impressive.

But they still end up 15% apart in group size.
