RE: Recoil Question??
Using the formula for determining recoil will let you compare various loadings in both gauges. A 3" 20-ga. with 1.25 oz of shot will recoil the same as a 12 using the same amount ofshot. In addition, with the right dimesions in the tube a 3" 20 can give patterns of over 70%. There is no way a 20 is going to give the recoil of a heavy 3"-3.5" 12 ga. It will kill as well as a 12, but at 25% shorter ranges than the 12s.
