Hello All,

I got a problem that I need some help with. I just bought some Muzzy 100s, 4 blade. When I tread the blades onto my arrows there is a gap between the ferrel and the arrow. Is that supposed to happen? I am using carbon arrows specifically Carbon Express 350's.

I had some thunder heads before these and it came with shims. Do I just have the wrong version of the muzzy's or do I need to get some of those shims. Could there be something wrong with the threaded inserts that are in my arrows?

Thanks
Tom
