OK= had a pkg of exersize bands in the closet, so--why not, cut some 1. -1/2 taper on the blue .55
band, put it on my black walnut Chalice ( took the red tubes off) and outside to try it out, temperature
14 degrees Fahrenheit ((cold-cold)). First shot,clay balls 242 FPS, finally settled out at 231-233, right decent for 14 degrees, I may use them quite a bit, better than I thought it would be. How bout that.
