Just use a "Hartin" crimp on them. Leave your press set up for 2-3/4 the way it usually is. Load the shell just like you would a 2-3/4" shell; after you drop your shot charge seat an overshot card then use your crimp starter station then finish with the final crimp. The overshot card will hold the shot in place. That is the way I do it. Can even write the shot size on the overshot card like the older shells.
