JPS,

I assume that the broadheads in question are the screw-on style of head. Remember that if the insert or halfout that the broadhead screwed into is not square to the centerline of the arrowshaft the tip will not runout true. This is pretty common problem to see on a lot of arrow setups. You will have to either bend the broadhead screw shaft to true it up some, or replace the insert for a better one. Muzzy's broadhead machining is some of the best in the industry for being true. It takes a bit of tinkering to get the arrow to spin test true, but its well worth the effort.

Aim Hard!
