Don't know where you have been the last 14 months or so but since BO was elected as POTUS, you have a better chance of picking up Pixie Sticks with your buttcheeks than you do locating certain primers.
That being said, there are some that are available and most likely you will have to send away and pay the hazmat fee to get them shipped to you. You may also not be able to find the exact ones you want but may have to substitute with what you can find.
Gander Mountain in my area has primers but the price is up from what they used to be, while Scheels has held it's price somewhat, but primers are gone in a hurry when they get them in. I call ahead most of the time and they set some aside for me if they get them in.
