I have used 100 grain muzzys in the past and they hit exactly like like my field points with my compound bow.
I switched to NAP thunderheads this year because they were on sale 10 bucks cheaper. They are within an inch at 30 yards but don't match up as well to the field points, they also are kind of noisy in flight. I haven't used them on a deer yet, but I am kind of wishing I had stuck with muzzys right now.
Fix it right the first time...
