RE: Slowest Speed
 

I would say in the 160-170 range.

I shoot for 277fps to 280fps. I like to hunt with one pin set at 25yds. and I also find that I can get good groups with fixed blade heads at that speed but no faster.

From my new bow, I want at least 250 fps for a 400+ grain arrow. However, this much speed isn' t necessary to kill a deer. My first bow--a Darton SL50 was accurate, but slow. I killed my first deer, a very large doe, with an arrow that had chronographed 173 fps. At 25 yards, I had a complete pass-thru that left the deer piled up at 60 yards. Quite a few years later, my then 14 year old son killed his first deer--a P&Y 8 point with a double lung shot from a very short draw bow set at 51lbs. Speed is nice for distance miscalculations, but not necessary for clean kills.
