Well I was going to put these pictures on a thread found this one so I guess I'll add these to Cal's since it's about rollcrimping. This old tool is not as easy as Cal's but works.
Rollcrimping short 10 with spreader for overshot wad. You have to adjust your filler wad so shot is down in shotcup far enough so the 12 gauge spreader will fit into the cup to center it. I also shortened my hull a little more with that handy dowell and exact-o-knife blade.
