Stan, recoil is not a factor with my 1/2 ounce shot load, in my .410. I could even go up to those super magnum 11/16 - 3/4 ounce loads you favor for later dove. Too many seem to think extra shot, or extra velocity will cover up lack of skill or just bad shots. Judge ranges better, practice shooting realistic targets instead of unrealistic easy birds, wait until birds are as near to the shooter as possible before moving your gun and shooter outcomes will drastically improve. It is the Indian not the bow or arrow.
I kill 100 plus dove every year with a 1/2 shot, that chronographs at 1260 fps. I have loads which top 1300+ fps, but they do not pattern as well as my preferred load of 1260 fps. You don't need more shot, or higher velocity to kill birds. I shoot a model 42, full choke .410, with 2 1/2" shells. I always make sure I know the real ranges, when ever possible when hunting. Dove are for the most part shot from a static position. I walk off my personal known limit of ability at 33 yards, from the shooting position, or use a bow hunters range finder if you have one. Limit shots to only birds within that area and your success rate will go up with whatever loads you use. Hope your season is full of great days in the field with friends and family.
