RE: horton steelforce 150?
It's a Horton Steelforce 150, DNK. I cannot remember the correct name of the broadhead. It is a 3 vane expanding head with a hollow ground cutting tip. Opens out to about an inch and a half. The name might have been Spider or something like that. Unfortunately I threw away the packaging and did not use them in the field until the following year. I can hardly remember what I ate for breakfast, so... anyway.
I did like the broadhead I used, and unfortunately when I went looking for some more I could not find them.
