When I first started shooting geese ad ducks steel out of a 20 , my friends and were surrised that the Federal Premium and Speed shok 2 3/4" ammo worked far better as far as patterns and killing goes than the Winchester 3" stuff I had brought along - both in #4.Well I kill mallards no problem with Federal Speed Shok 2 3/4" 3/4 oz #4 steel so I imagine it would be plenty on roosters.
