I can remember my first compound bow, it was a Bear Whitetail Hunter, that bad boy was a screamer I tell you. I practiced a lot and I could hit a pie plate at 60 yds with that bow.
During archery season I was on my deer lease on the side of a hill and the buck I wanted to shoot was my guess 55-60 yds downhill from me. I took careful aim as he stood there broadside and looking at me. I pulled back the 60lb bow, set the sight where I thought I needed it, and let it fly. Of course, the scene went into slow motion as it is today as I reflect back some 40+ years, I watched as my Bear aluminum shaft arrow carrying my Bear broadhead, launched from my Bear bow was air born heading towards the deer of my lifetime, the arc was beautiful as it was nearing the buck of my lifetime. Of course, I could not tell how many feet that wonderful flying setup was from the buck but just before it plunged deep into his ribcage he lowered his body and when the arrow flew over him he stood back up as if he was asking/tempting me if I wanted another try. Of course, I did, so out came another arrow from my Bear quiver but as I drew the arrow back the buck decided not to temp fate twice I guess and he took off.
I don't know for sure what the fps was on it back in the day, but I did a net search today and after finding a pic of the bow I found a video of a man who shot three arrows through a chronograph, 173, 174, & 175 fps, using vintage Bear heavy aluminum arrows and field points.
I never got to pull another arrow back on that buck, but a month later during rifle season, he did not duck under my 7mm Express 150 gr load and he hangs on my wall today.
