In my opinion pretty much all of these 209 primers are made for shotgun shells and are adapted for muzzleloaders. It has been a few years since I have really reloaded shotshells but for 20 plus years I never shot a factory load. Back then the Federal primers were considered the hottest and usually produced the highest pressures. After that came the Remington, then the CCI and the Winchester were considered slowest and normally gave the lowest pressures, but also left more unburned powder residue. I have to believe that this still pretty much holds true now. I have used Federal and Remington and Winchester primers in my Knight and really don't see any discernable difference between any of them. Any one who is shooting pellets would really have to prove any difference to me as the fluctuation in the pellets would have to be much more of a factor than any small differences in primers, at least that is what I believe.
