Having shot considerable skeet with an 870 in .410, I can tell you that cycling the action becomes second nature and takes no meaningful time away from proper shooting. In fact, the speed of an autoloader can be a liability when the second shot goes off without due deliberation (i.e. proper sight picture, lead, swing, etc.). You see this quite a bit in the field, where auto shooters break shots that are wasted. Give it a try. You might just be pleasantly surprised at the results.
