I'm kind of limited to what my local gun shop handles. I'm sure he has the W209 primers.
Otherwise i'd have to order online, and get banged the HazMat fee.
I did try the Remington Kleanbore once to see if it would fire. It did fire, but had a slight delay. I had already fired 25 rounds, so the BP needed cleaning. Maybe with a clean BP they would have fired better. Not something i'd try hunting though.
