Salopian, could you expound on those "scientific tests" that proved imp modified and full are the best all around chokes for hunting? Whoever came up with the test sure as devil never hunted Ruffed Grouse in thick cover. I just can't imagine such a generalization holds true for all types of game. Maybe the tests showed such choking suited English driven birds or waterfowl. And since we are already into our uncommon language usages, I was under the general impression we do a lot more bird hunting in USA whereas you do a lot more shooting of birds in British Isles. The distinction being whether the guns are moving to find birds or are waiting for them to arrive on cue. We do some shooting too for Doves and waterfowl.
