I use the TC red rubbery thing for my 209 primers. Holds 6 or 7 and its flexible so you can get them out easily and the backside of the holes are closed so debris doesnt get into the business end of them. they are like $5 or so. and since they are soft, they don't rattle around with other things in your pocket.
I got one of those, and one that holds three and has a chain on it that I attached to my front sling-swivel.
Worked great hunting. This site, as usual, comes through with good advice.
