I just bought this nifty little tool by RCBS:
http://tinyurl.com/3mbvz28. No shell holders required any more for hand priming.
It works a little slower than my Hornady hand primer but I was having trouble getting the shell holders I needed for my Hornady one and keeping them straight as to which for which brass. It can ding the rim on your brass if you're not careful.
Over all pretty good tool though, works very well even if it is slower.
