Where does your friend in Maine live? Everyone now and then 57 size primers show up at the Kittery Trading Post when someone turns them in for store credit.

The way to use 209 primers in 57 size hulls is rather simple. Push out the spent 57 primer. Put a spent 209 size primer in the reloader and push down, it will go in harder than normal but with not a lot more effort. Then deprime the hull again and seat a new 209 primer.

I would like to know what 12brd's method of using 57 primers in 209 sized shells is. Perhaps it's something like putting a piece of tape around the primer.
