As long as I'm over what I consider a minimum adequate amount of energy/momentum for the distance I'm willing to shoot I wouldn't give up any speed for energy.
Good enough
Syl IYO what do you consider adequate energy?
For inside 40 yards I like to have around or better than 65 ft/lb of KE at point of release.
Actually I think this was answered several times in the other thread. Several people said that delivering energy over the minimum needed only winds up wasted in the ground after it passes through the deer.
It got a little hard to follow with all the posts not showing up[8D]
