Though not a huge fan, CCI seems to be keeping up with demand more than the others. I've seen them at BassPro and Academy Sports in small rifle, large rifle, and pistol. Federals are more sporadic, and I've only seen pistol and small rifle for those maybe twice in the last 18-20 months at BassPro only. And, only the standard Federal. Good luck finding Federal Match. Both of these stores are allowing purchase of a brick. Academy was at 1 brick per customer and BP at 2 per customer. Not sure what they are now. They only post the limit when they have the primers in stock. Most large retailers like BP (Cabela's), Academy, Sportsman's Warehouse and others only sell primers and powder for in store purchases only. They will always show out of stock online. You have to either call the store or go there and check in person. I've been monitoring 11 different online sellers for the past 24 months looking for primers and have come up with zero so far for what I'm looking for in particular. Now of course, you can go on Gunbroker.com and pay 4 times MSRP + shipping (usually between $30 - $50) and get all you want. I saw a bid on a brick of Federal GM215M for $415 last night. I'm not quite that desperate just yet.
