So many people think faster is better! but it isn't, necessarily. Lead shot loads don't respond well to faster velocity - patterns tend to suffer, with more deformed pellets and very little if any increase in target breaking ability per individual pellet. Longer shot strings are another fault of high velocity lead loads. An unskilled shooter may scratch down a few more targets with a stray pellet from a long shot string, but a good shooter will get fewer solid hits. And recoil is a real problem too. Nobody shoots better with more recoil, less is better. Target shot shells have been pretty much perfected over the last hundred years, most of the "new and improved" stuff is marketing. Exceptions abound for hunting loads, but that's another topic.
