Just bought some 100 grain Satellite broadheads.I've never handled broadheads before as I've only hunted small game, but I'm going out for Deer in the fall.

I want to install the smaller aux. blades, but I'm not sure of the proper way. Theres a small slit on both sides which they go into, but i'm not sure how to get them in there. should I slide them in from the back of the slit? I've tried, but it's a really tight fit. Any suggestions?

thanks
