I have used these "flared blunts" ( I can't remember what the correct name is) with some success . I bought them from Ted fry . I also have used broadheads, which seemed to work out better , in my opinion.
Bow wise, I used the same bow I hunt everything else with.

That name, Robbie Robinson sounds familiar. Have you tried looking at old SDA's member lists? I seem to remember him as a target shooter? The only other Robinson's I remember were Don&Gala from D&G Archery. Another source of info might be CBH. I remember those shoots but never made it up there. Just looked at CBH website and that club still has that shoot coming up. The Bigfoot is a "logo". Why the difference in color I don't know.

also found this. from the company

thanks everyone for the posts,   I did go after them before I think I used 38 special casings an we"d put #9 lead shot inside first with some hot glue then put the un tapered arrow in.   I think the casings bounced off trees better but at the time we were shooting pretty heavy bows,,,,, now I think anything I use would bounce off trees.   I was more curious about the calls or the shaking the two nickles in the hand trick.    someone else PM'd me and said just throw handfuls of corn and squirrel feed out a few days before going they'll be there just set up and wait like deer hunting. 

I lived in Redding and Cottonwood and heard nothing about that club it must be pretty old.

The Bigfoots must be female - 

If you are happy..you are doing it right. If you find yourself unhappy, you might first try shooting less. If on the other hand you enjoy unhappiness try lots of other archers ideas and shoot several different bows weekly or even daily if you aren't unhappy enough..if this becomes tiring maybe go back to what you think you originally were doing , if you can still remember and if you haven't entirely lost the magic.

Did you try a Google search? I had some old buckles I tried to ID and Google search gave me some answers.Take a pic in Google Search.
The only Robbie Robinson I know of was a member of The Band a rock group from the 60s and 70s and Bob Dylan's band back in the 60s.

For $53.00 a pint, i think i'll pass.   .. Glad it's working well for you. Too rich for my blood.
